Cyclin-dependent kinase 1 (CDK1, also known as CDC2/p34cdc2) is the essential and universally conserved serine/threonine kinase that drives the G2/M transition and mitotic progression in all eukaryotes. CDK1 is unique among CDKs in being absolutely required for cell division in mammals. The active holoenzyme consists of CDK1 bound to cyclin B1 (principally) or cyclin A, with CKS1/2 serving as phospho-adaptors that promote multisite substrate phosphorylation. CDK1 activity is tightly regulated through activating phosphorylation at Thr161 by CAK (CDK7-cyclin H) and inhibitory phosphorylation at Thr14 and Tyr15 by WEE1 and PKMYT1, which is reversed by CDC25 phosphatases at mitotic entry. CDK1 phosphorylates substrates on S/T-P motifs and has over 1000 documented substrates, including lamins (nuclear envelope breakdown), condensins (chromosome condensation), and numerous mitotic machinery proteins. As a master regulator of cell division, CDK1 has been documented to phosphorylate many proteins involved in diverse processes beyond mitosis (transcription, metabolism, organelle dynamics), but its core evolved function is as the essential mitotic kinase

GO:0005634
nucleus
|
IBA
GO_REF:0000033 |
ACCEPT |
Summary: CDK1 localizes to the nucleus during G2 and at mitotic entry. CDK1-cyclin B complexes shuttle between cytoplasm and nucleus, with activation detected at centrosomes and then across nuclear compartments at nuclear envelope breakdown.
Reason: Nuclear localization is well-established and essential for CDK1 function in regulating nuclear substrates including lamins. The IBA annotation is phylogenetically supported across diverse eukaryotes.

GO:0000086
G2/M transition of mitotic cell cycle
|
IBA
GO_REF:0000033 |
ACCEPT |
Summary: CDK1 is THE essential kinase for G2/M transition - the defining core function of this protein. CDK1 drives the bistable switch into mitosis through phosphorylation of numerous mitotic substrates.
Reason: This is the canonical, essential function of CDK1. CDK1 is uniquely essential among CDKs for mammalian cell cycle progression and specifically drives G2/M transition. The IBA annotation reflects deeply conserved function across all eukaryotes.
|
|
GO:0000307
cyclin-dependent protein kinase holoenzyme complex
|
IBA
GO_REF:0000033 |
ACCEPT |
Summary: CDK1 functions as part of a holoenzyme complex with cyclin partners (principally cyclin B1, also cyclin A) and CKS subunits (CKS1/2) that act as phospho-adaptors.
Reason: CDK1 requires cyclin binding for activity - this is fundamental to its function. The holoenzyme complex is the active form of the kinase.
|
|
GO:0004693
cyclin-dependent protein serine/threonine kinase activity
|
IBA
GO_REF:0000033 |
ACCEPT |
Summary: CDK1 is a prototypical cyclin-dependent kinase with serine/threonine kinase activity (EC 2.7.11.22/23). It requires cyclin binding for catalytic activity and phosphorylates S/T-P motifs.
Reason: This is the core molecular function of CDK1. The enzyme activity is well-characterized biochemically with defined substrate specificity for S/T-P motifs.
|
|
GO:0007095
mitotic G2 DNA damage checkpoint signaling
|
IBA
GO_REF:0000033 |
ACCEPT |
Summary: CDK1 activity is the target of the G2 DNA damage checkpoint. The checkpoint operates through inhibition of CDC25 phosphatases and activation of WEE1/PKMYT1, which maintain CDK1 in an inactive, phosphorylated state.
Reason: CDK1 is central to G2 checkpoint signaling as its activity is the regulated output of the checkpoint pathway. DNA damage prevents CDC25-mediated activation of CDK1.
|
|
GO:0006338
chromatin remodeling
|
IEA
GO_REF:0000108 |
KEEP AS NON CORE |
Summary: CDK1 phosphorylates chromatin-associated proteins during mitosis as part of chromosome condensation. However, CDK1 is not a dedicated chromatin remodeler - this is a downstream consequence of its mitotic role.
Reason: While CDK1 does phosphorylate chromatin-associated substrates, this is part of its broader role in mitotic progression rather than a core chromatin remodeling function.
|
|
GO:0006357
regulation of transcription by RNA polymerase II
|
IEA
GO_REF:0000108 |
KEEP AS NON CORE |
Summary: CDK1 can phosphorylate the RNA Pol II CTD, but this is not its core function. CDK1's transcriptional regulation role is largely through mitotic transcriptional shutdown.
Reason: CDK1 phosphorylation of RNA Pol II CTD and transcriptional regulators occurs but is peripheral to its core cell cycle function.

symbiont entry into host cell
|
IEA
GO_REF:0000108 |
MARK AS OVER ANNOTATED |
Summary: This appears to be derived from CDK1 role in viral infection processes. CDK1 may be exploited by viruses but this is not an evolved function.
Reason: Viral exploitation of host cell cycle machinery does not represent an evolved function of CDK1. This annotation conflates pathogen hijacking with host protein function.
|
|

nucleotide binding
|
IEA
GO_REF:0000043 |

Summary: CDK1 binds ATP as a substrate for its kinase activity. This is a generic annotation that follows from having kinase activity.
Reason: While true, this is a very general annotation implied by the kinase activity. The more specific ATP binding term is more informative.
|
|
GO:0001618
virus receptor activity
|
IEA
GO_REF:0000043 |
REMOVE |
Summary: This annotation appears to be based on UniProt keywords. CDK1 is not a virus receptor in the canonical sense - viruses may exploit CDK1 function but it is not a cell surface receptor for viral entry.
Reason: CDK1 is an intracellular kinase, not a virus receptor. This annotation is misleading and likely results from misinterpretation of CDK1's role in viral replication cycles.
|

Reason: Centrosomal localization is well-established and functionally important for CDK1 activation and mitotic spindle organization.
|
|
GO:0005819
spindle
|
IEA
GO_REF:0000044 |
ACCEPT |
Summary: CDK1 localizes to the mitotic spindle where it phosphorylates spindle-associated substrates to regulate spindle assembly and function.
Reason: Spindle localization is well-documented and functional for mitotic regulation.
|
|
GO:0006915
apoptotic process
|
IEA
GO_REF:0000043 |
MARK AS OVER ANNOTATED |
Summary: CDK1 phosphorylates apoptosis-related proteins including survivin (Thr34), caspase-9, and Bcl-2 family members as part of its extensive substratome. However, apoptosis is NOT a core function of CDK1. CDK1 phosphorylates survivin to maintain its anti-apoptotic activity during mitosis, preventing inappropriate cell death during cell division. This represents phosphorylation of apoptotic regulators during normal cell cycle, not an evolved apoptotic function.
Reason: This is the quintessential OVER-ANNOTATION. CDK1's core function is cell cycle control. The fact that CDK1 phosphorylates survivin and other apoptosis-related proteins among its 1000+ substrates does not make apoptosis its function. This is analogous to annotating a transcription factor to all processes involving its target genes. The 2023 Massacci review explicitly notes CDK1's apoptosis-related substrates as part of the expanded CDK1 substratome but this represents downstream effects of cell cycle kinase activity, not an evolved apoptotic function.

Reason: True but very generic. Implied by kinase activity.
|
|
GO:0048511
rhythmic process
|
IEA
GO_REF:0000043 |
KEEP AS NON CORE |
Summary: CDK1 activity cycles with the cell cycle, which is a rhythmic process. CDK1 also has connections to circadian rhythm.
Reason: The cell cycle is rhythmic, and CDK1 has been implicated in circadian regulation, but rhythmic process is not the core function.
|
|
GO:0051301
cell division
|
IEA
GO_REF:0000043 |
ACCEPT |
Summary: CDK1 is essential for cell division. This is its core biological process.

Summary: CDK1 phosphorylation of survivin maintains its anti-apoptotic function during mitosis. However, this represents CDK1 ensuring cell survival during division, not an evolved anti-apoptotic function.
Reason: CDK1 phosphorylates survivin to maintain cell viability during mitosis - this is part of ensuring successful cell division, not a dedicated anti-apoptotic function. Annotating CDK1 to apoptosis regulation conflates substrate effects with core function.

Q: Should CDK1 be annotated to apoptotic process given that it phosphorylates survivin and other apoptosis regulators? Review consensus is NO - this is over-annotation. CDK1 phosphorylates over 1000 substrates as part of its cell cycle function. Phosphorylating apoptosis regulators to maintain cell viability during division is not the same as having apoptosis as an evolved function.
Q: How should the extensive Reactome pathway annotations resulting in many duplicate localization terms be handled? Multiple Reactome pathway references for the same localization term create redundancy but add evidence.

BEFORE YOU BEGIN RESEARCH: You MUST verify you are researching the CORRECT gene/protein. Gene symbols can be ambiguous, especially for less well-characterized genes from non-model organisms.
DO NOT PROCEED WITH RESEARCH ON A DIFFERENT GENE. Instead:
- State clearly: "The gene symbol 'CDK1' is ambiguous or literature is limited for this specific protein"
- Explain what you found (e.g., "Found extensive literature on a different gene with the same symbol in a different organism")
- Describe the protein based ONLY on the UniProt information provided above
- Suggest that the protein function can be inferred from domain/family information
Please provide a comprehensive research report on the gene CDK1 (gene ID: CDK1, UniProt: P06493) in human.
The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.

Plan and verification
- Verified identity: Human CDK1 (cyclin-dependent kinase 1), UniProt P06493, CMGC family serine/threonine protein kinase with canonical protein kinase domain; literature and structures confirm human CDK1 in complexes with cyclin B and CKS proteins (Brown 2015) (brown2015cdk1structuresreveal pages 1-2). Organism and family/domain assignment align with the provided UniProt context (brown2015cdk1structuresreveal pages 1-2).
- Evidence strategy: Emphasize recent peerβreviewed reviews and structural/cellβcycle analyses (2023β2024 emphasis where available), focusing on: enzymatic function and motifs; activation/inhibition circuitry; cyclin partners and localization; pathway context; nonβmitotic roles; and translational applications.
Human CDK1: key concepts and definitions
- Enzymatic class and essential role: CDK1 is a conserved serine/threonine protein kinase (EC 2.7.11.22/23) that is the only CDK essential for mammalian cell-cycle progression; it drives the G2βM transition and Mβphase processes (Brown 2015; Massacci 2023) (brown2015cdk1structuresreveal pages 1-2, massacci2023thecyclindependentkinase pages 1-2).
- Substrate specificity and motifs: CDK1 typically phosphorylates S/TβP motifs. Substrate selection is refined by cyclin docking interfaces and the CKS subunit, which promotes priming/multisite phosphorylation and processivity on CDK substrates (Brown 2015; Massacci 2023) (brown2015cdk1structuresreveal pages 1-2, massacci2023thecyclindependentkinase pages 1-2).
- Activation and inhibition logic: The catalytic activation segment T161 must be phosphorylated by the CDKβactivating kinase (CAK, CDK7βcyclin H), while T14 and Y15 are inhibitory sites set by WEE1/PKMYT1 and removed by CDC25 phosphatases (CDC25A/B/C) to trigger the switch into mitosis (Lemonnier 2020; Massacci 2023; Wang 2023) (lemonnier2020theg2tomtransition pages 1-2, massacci2023thecyclindependentkinase pages 1-2, wang2023targetingcdk1in pages 1-2).
- Cyclin partners and cofactors: The principal mitotic partner is cyclin B1 (also cyclin A can bind in some contexts). CKS1/2 act as phosphoβadaptors that dock to primed sites and facilitate multiβsite substrate phosphorylation, shaping timing and ordering of mitotic events (Brown 2015; Massacci 2023) (brown2015cdk1structuresreveal pages 1-2, massacci2023thecyclindependentkinase pages 1-2).
- Localization and timing: CDK1βcyclin complexes distribute between cytoplasm and nucleus. At mitotic entry, activation is detected at centrosomes and then across nuclear/kinetochore/spindle compartments around nuclear envelope breakdown (NEBD), coordinating mitotic onset (Brown 2015; Lemonnier 2020; Massacci 2023) (brown2015cdk1structuresreveal pages 1-2, lemonnier2020theg2tomtransition pages 1-2, massacci2023thecyclindependentkinase pages 1-2).
- Pathway context: CDK1 sits within a bistable βG2/M switchβ governed by PLK1 (promotes Cdc25, inhibits Wee1), and by the GreatwallβPP2AβB55 phosphatase axis that times dephosphorylation versus phosphorylation waves. Mitotic exit proceeds as APC/C activation and phosphatase reactivation reverse CDK1βdriven phosphorylation (Lemonnier 2020; Brown 2015; Massacci 2023) (lemonnier2020theg2tomtransition pages 1-2, brown2015cdk1structuresreveal pages 1-2, massacci2023thecyclindependentkinase pages 1-2).
Recent developments and latest research (emphasis 2023β2024)
- Comprehensive 2023 synthesis of nonβmitotic roles: A 2023 British Journal of Cancer review catalogues CDK1βs roles beyond mitosisβtranscriptional control, mitochondrial metabolism (e.g., Drp1 fission; Complex I and SIRT3 regulation), apoptosis (caspase-9, Bclβ2 family, survivin), Golgi remodeling, endocytosis and nucleocytoplasmic transportβexpanding the βCDK1 substratomeβ and cancerβrelevance of these functions (Massacci 2023) (massacci2023thecyclindependentkinase pages 3-4, massacci2023thecyclindependentkinase pages 1-2, massacci2023thecyclindependentkinase pages 7-9).
- Structural basis and selectivity levers: Human CDK1βcyclin BβCKS complexes reveal differences versus CDK2 that affect stability, activationβsegment control and substrate sequence preferences; such differences are potential avenues for CDK1βselective inhibitor design (Brown 2015) (brown2015cdk1structuresreveal pages 1-2).
- Phosphataseβcentric view of the mitotic switch: Recent conceptual advances synthesize how GreatwallβPP2AβB55, Cdc25 and Wee1/Myt1 orchestrate the irreversible G2βM transition and timing through sequential dephosphorylationsβhighlighting phosphatases as equally central as kinases for mitotic control (Lemonnier 2020) (lemonnier2020theg2tomtransition pages 1-2).
- Oncogenic regulation via Tyr15 and resistance: Phosphoproteomic and signaling analyses link CDK1 Tyr15 phosphorylation to drug resistance circuitry (e.g., ERBB2/SRC/BRK) and show cancerβtypeβspecific activation states; CDK1 is transcriptionally/proteomically upregulated across many tumors (Massacci 2023) (massacci2023thecyclindependentkinase pages 7-9).
Current applications and realβworld implementations
- Therapeutic positioning and inhibitors: CDK1 is widely overexpressed in tumors and is a prioritized target; however, firstβgeneration panβCDK inhibitors suffered from toxicity. Newer strategies include more selective CDK1 tool compounds (e.g., ROβ3306), combination regimens, and targeting upstream gatekeepers (WEE1/PKMYT1) to modulate the CDK1 switch and radiosensitize or chemosensitize tumors (Wang 2023; Massacci 2023) (wang2023targetingcdk1in pages 1-2, massacci2023thecyclindependentkinase pages 9-9).
- Biomarker and resistance context: Analyses across The Cancer Genome Atlas show CDK1 expression elevation in roughly 71% (17/24) of cancer types examined, consistent with proliferative state and poor outcomes; inhibitory Y15 phosphorylation circuitry can contribute to resistance to taxanes and kinase inhibitors, suggesting actionable biomarkers and combination partners (Wang 2023; Massacci 2023) (wang2023targetingcdk1in pages 1-2, massacci2023thecyclindependentkinase pages 7-9).
Expert opinions and analysis from authoritative sources
- Brown 2015 (Nature Communications): CDK1 is uniquely essential; structures of CDK1 with cyclin B and CKS define conserved activation principles and unique features differentiating it from CDK2, with implications for substrate recognition and inhibitor selectivity (brown2015cdk1structuresreveal pages 1-2).
- Lemonnier 2020 (Cell Division): Emphasizes phosphatase control (PP2AβB55, Cdc25) as the counterweight to kinase networks in G2βM, explaining robustness and irreversibility of mitotic entry (lemonnier2020theg2tomtransition pages 1-2).
- Massacci 2023 (British Journal of Cancer): Integrates curated substrates and upstream regulators, argues for broad nonβmitotic functions of CDK1 in cancer biology, and frames therapeutic opportunities and open questions (massacci2023thecyclindependentkinase pages 1-2, massacci2023thecyclindependentkinase pages 3-4, massacci2023thecyclindependentkinase pages 6-7, massacci2023thecyclindependentkinase pages 7-9).
- Wang 2023 (NPJ Precision Oncology): Reviews targeting CDK1 in cancer, summarizing regulatory mechanisms, expression patterns across cancers, and development status of direct and indirect (checkpointβlevel) inhibitors (wang2023targetingcdk1in pages 1-2).
Relevant statistics and data from recent studies
- Tumor overexpression prevalence: Across large cancer datasets, CDK1 expression is elevated in about 70.8% (17/24) of cancer types, reinforcing its translational relevance as a target and biomarker (Wang 2023) (wang2023targetingcdk1in pages 1-2).
- Substrate landscape: Contemporary curation collates many direct human CDK1 substrates across mitotic and nonβmitotic processes, with siteβ and outcomeβlevel annotations (activation vs inhibition), providing a reference βsubstratomeβ for hypothesis generation (Massacci 2023) (massacci2023thecyclindependentkinase pages 6-7).
- Resistance circuitry: Cancerβtypeβspecific modulation of CDK1 activation state (e.g., Tyr15) correlates with drug resistance mechanisms, including ERBB2/SRC/BRK signaling, informing combination therapy design (Massacci 2023) (massacci2023thecyclindependentkinase pages 7-9).
Key substrates and cellular localizations (selected examples)
- Mitotic machinery and cytoskeleton: CDK1 phosphorylates numerous spindle, kinetochore, and microtubuleβassociated proteins (e.g., KIF11/EG5, BUB1B, MAP4, intermediate filaments such as vimentin and lamin A), coordinating chromosome segregation and cell morphology changes; localization includes centrosomes, nucleus, kinetochores and spindle during Mβphase (Brown 2015; Massacci 2023) (brown2015cdk1structuresreveal pages 1-2, massacci2023thecyclindependentkinase pages 6-7).
- Transcription, metabolism and organelles: Curated substrates include regulators of transcription/translation and mitochondrial and Golgi proteins (e.g., Drp1/mitochondrial fission; GRASP65/GM130 for Golgi remodeling), highlighting nonβmitotic localization and functions (Massacci 2023) (massacci2023thecyclindependentkinase pages 3-4, massacci2023thecyclindependentkinase pages 7-9).

Conclusions
Human CDK1 (P06493) is the essential mitotic CDK that integrates cyclin docking, CKSβfacilitated multisite phosphorylation, and phosphoregulation at T161/T14/Y15 to control the abrupt, robust G2βM transition. Recent work emphasizes the equal importance of phosphatase networks (GreatwallβPP2AβB55), and expands CDK1 biology beyond mitosis to transcription, metabolism, membrane trafficking, and apoptosis. In oncology, CDK1 is frequently upregulated and functionally implicated in resistance circuitry; translational strategies include direct inhibition and modulation of upstream checkpoint kinases (e.g., WEE1), often in rational combinations. Structural distinctions from CDK2 and curated, siteβresolved substrate maps now provide concrete levers for designing selective inhibitors and for prioritizing actionable substrates in disease contexts (brown2015cdk1structuresreveal pages 1-2, lemonnier2020theg2tomtransition pages 1-2, massacci2023thecyclindependentkinase pages 1-2, wang2023targetingcdk1in pages 1-2).

description: Cyclin-dependent kinase 1 (CDK1, also known as CDC2/p34cdc2) is the
essential and universally conserved serine/threonine kinase that drives the
G2/M transition and mitotic progression in all eukaryotes. CDK1 is unique
among CDKs in being absolutely required for cell division in mammals. The
active holoenzyme consists of CDK1 bound to cyclin B1 (principally) or cyclin
A, with CKS1/2 serving as phospho-adaptors that promote multisite substrate
phosphorylation. CDK1 activity is tightly regulated through activating
phosphorylation at Thr161 by CAK (CDK7-cyclin H) and inhibitory
phosphorylation at Thr14 and Tyr15 by WEE1 and PKMYT1, which is reversed by
CDC25 phosphatases at mitotic entry. CDK1 phosphorylates substrates on S/T-P
motifs and has over 1000 documented substrates, including lamins (nuclear
envelope breakdown), condensins (chromosome condensation), and numerous
mitotic machinery proteins. As a master regulator of cell division, CDK1 has
been documented to phosphorylate many proteins involved in diverse processes
beyond mitosis (transcription, metabolism, organelle dynamics), but its core
evolved function is as the essential mitotic kinase

review:
summary: CDK1 localizes to the nucleus during G2 and at mitotic entry.
CDK1-cyclin B complexes shuttle between cytoplasm and nucleus, with
activation detected at centrosomes and then across nuclear compartments
at nuclear envelope breakdown.
action: ACCEPT
reason: Nuclear localization is well-established and essential for CDK1
function in regulating nuclear substrates including lamins. The IBA
annotation is phylogenetically supported across diverse eukaryotes.

review:
summary: CDK1 is THE essential kinase for G2/M transition - the defining
core function of this protein. CDK1 drives the bistable switch into
mitosis through phosphorylation of numerous mitotic substrates.
action: ACCEPT
reason: This is the canonical, essential function of CDK1. CDK1 is
uniquely essential among CDKs for mammalian cell cycle progression and

summary: CDK1 functions as part of a holoenzyme complex with cyclin
partners (principally cyclin B1, also cyclin A) and CKS subunits
(CKS1/2) that act as phospho-adaptors.

serine/threonine kinase activity (EC 2.7.11.22/23). It requires cyclin
binding for catalytic activity and phosphorylates S/T-P motifs.

label: mitotic G2 DNA damage checkpoint signaling
evidence_type: IBA

review:
summary: CDK1 activity is the target of the G2 DNA damage checkpoint. The
checkpoint operates through inhibition of CDC25 phosphatases and
activation of WEE1/PKMYT1, which maintain CDK1 in an inactive,
phosphorylated state.
action: ACCEPT
reason: CDK1 is central to G2 checkpoint signaling as its activity is the
regulated output of the checkpoint pathway. DNA damage prevents
CDC25-mediated activation of CDK1.

summary: CDK1 phosphorylates chromatin-associated proteins during mitosis
as part of chromosome condensation. However, CDK1 is not a dedicated
chromatin remodeler - this is a downstream consequence of its mitotic
role.

label: apoptotic process
evidence_type: IEA
original_reference_id: GO_REF:0000043
review:
summary: CDK1 phosphorylates apoptosis-related proteins including survivin
(Thr34), caspase-9, and Bcl-2 family members as part of its extensive
substratome. However, apoptosis is NOT a core function of CDK1. CDK1
phosphorylates survivin to maintain its anti-apoptotic activity during
mitosis, preventing inappropriate cell death during cell division. This
represents phosphorylation of apoptotic regulators during normal cell
cycle, not an evolved apoptotic function.
action: MARK_AS_OVER_ANNOTATED
reason: This is the quintessential OVER-ANNOTATION. CDK1's core function
is cell cycle control. The fact that CDK1 phosphorylates survivin and
other apoptosis-related proteins among its 1000+ substrates does not
make apoptosis its function. This is analogous to annotating a
transcription factor to all processes involving its target genes. The
2023 Massacci review explicitly notes CDK1's apoptosis-related
substrates as part of the expanded CDK1 substratome but this represents
downstream effects of cell cycle kinase activity, not an evolved
apoptotic function.

description: >-
CDK1 is the essential cyclin-dependent kinase for cell division. It forms
holoenzyme complexes with cyclin B1 (principally) or cyclin A, and with CKS1/2
phospho-adaptors. CDK1 phosphorylates substrates on S/T-P motifs and drives
the G2/M transition by phosphorylating over 1000 substrates including lamins,
condensins, and numerous mitotic machinery proteins.

suggested_questions:
- question: >-
Should CDK1 be annotated to apoptotic process given that it phosphorylates
survivin and other apoptosis regulators? Review consensus is NO - this is
over-annotation. CDK1 phosphorylates over 1000 substrates as part of its cell
cycle function. Phosphorylating apoptosis regulators to maintain cell viability
during division is not the same as having apoptosis as an evolved function.
- question: >-
How should the extensive Reactome pathway annotations resulting in many
duplicate localization terms be handled? Multiple Reactome pathway references
for the same localization term create redundancy but add evidence.
