Gene Description

CBL (c-Cbl) is a cytoplasmic RING-type ubiquitin E3 ligase and signaling adaptor that is recruited to activated tyrosine-kinase complexes. Its N-terminal tyrosine kinase-binding module recognizes selected phosphotyrosine motifs, while a linker and RING domain recruit an E2 ubiquitin-conjugating enzyme; Tyr371 phosphorylation helps relieve autoinhibition. Its proline-rich region binds SH3-domain adaptors, and phosphorylated CBL can itself recruit SH2-domain partners. CBL ubiquitinates receptors and associated signaling proteins, contributing to receptor trafficking and attenuation of growth-factor signals. Ubiquitination can also regulate signaling without accelerating degradation: CBL and CBLB redundantly modify ligand-engaged LAG3, enabling its inhibitory activity in T cells. CBL can act through noncatalytic interactions as well, with context-dependent effects on survival signaling. It acts in the cytosol and on the cytoplasmic side of membrane-associated complexes. Germline CBL variants cause a Noonan-like disorder with variable predisposition to juvenile myelomonocytic leukemia; disease-associated linker/RING variants can disrupt ubiquitination and receptor trafficking.

GO Term Evidence Action Reason
GO:0000209 protein polyubiquitination
IEA
GO_REF:0000107
ACCEPT
Summary: Retain polyubiquitination as an executed CBL process.
Reason: CBL catalyses ubiquitin-chain assembly rather than merely being a substrate of it. The human LAG3 study provides an independent target basis, including CBL/CBLB double-loss and individual rescue and K63-chain controls. The original rat/Ensembl transfer is preserved; its specific donor experiment was not independently reconstructed.
Supporting Evidence:
GO_REF:0000107
GO:0001784 phosphotyrosine residue binding
IEA
GO_REF:0000002
ACCEPT
Summary: Retain phosphotyrosine recognition by the TKB domain.
Reason: The domain prediction agrees with CBL phosphopeptide structures and binding measurements in PMID:18273061 and PMID:22266821. This is CBL recognizing phosphorylated residues on a ligand; it is distinct from other proteins recognizing phosphorylated CBL. Positive target-peptide results do not imply that every tested receptor peptide binds.
Supporting Evidence:

GO:0004842 ubiquitin-protein transferase activity
IEA
GO_REF:0000002
ACCEPT
Summary: Retain the broad ubiquitin-transferase activity.
Reason: The RING-domain mapping agrees with the experimentally established E3 activity in PMID:10514377 and PMID:22266821. CBL recruits and activates an E2; the broad parent does not imply that CBL forms a HECT-like catalytic thioester. The existing, more informative E3 assertion supplies the core function.

ACCEPT
Summary: Retain ubiquitin-transferase activity in EGFR trafficking.
Reason: The source links CBL ligase activity to Eps15 recruitment and ligand-bound EGFR entry into coated pits. This agrees with independent direct E3 evidence; it does not assign the catalytic activity of E2 or EGFR to CBL.

Independent PMID:15737992 supplies the CBL TKB–APS phosphopeptide structure and additional calorimetry. Together these establish CBL recognition of the partner phosphotyrosine motif. The exact machine partner remains unchanged, and the rat whole-protein construct is distinguished from the human annotation.

That is not evidence that the native FLT1 peptide shares the positive interface mapped for the other partners. The original annotation may refer to a different construct or assay not resolved here.

Reason: PMID:18273061 Fig. 4H reports endogenous GRB2 co-immunoprecipitation with full-length CBL and TKB mutants in 293T cells. This control supports association but does not isolate the GRB2 contact domain; TKB peptide structures from other partners are not transferred to GRB2. The exact curated UniProt edge and independent PMID:11997436 support the interaction. The latter establishes an SH3-mediated recruitment mode, already represented in the core, but does not establish that this original assay uses the same domain rather than another GRB2 contact or a larger complex.

Reason: PMID:28514442 supplies BioPlex affinity-purification/mass-spectrometry association evidence. The original CBL–GRB2 target table and contact surface were not independently inspected. The exact curated UniProt edge and independent PMID:11997436 support the interaction. The latter establishes an SH3-mediated recruitment mode, already represented in the core, but does not establish that this original assay uses the same domain rather than another GRB2 contact or a larger complex. Retain generic non-core binding under the standing policy; partner identity alone is insufficient for this domain-specific replacement.

Summary: Refine the supported CBL–YWHAH (14-3-3 eta) interaction to 14-3-3 protein binding.
Reason: The exact Q04917 partner is a 14-3-3 family member and its CBL association is independently corroborated in the reviewed UniProt interaction record. The original BioPlex target table was not independently inspected; an affinity association does not alone establish a purified binary interface. GO:0071889 specifies binding to this protein class; it does not assign phosphoserine recognition to CBL or specify the interaction surface. This is a more informative description of the retained qualitative interaction, with the original assay-access limit preserved.

Reason: The PMID:28514442 source and UniProt list the exact interaction partner. The original BioPlex target-specific table was not independently recovered.

KEEP AS NON CORE
Summary: Retain CBLB coassociation in the IFT20 complex.
Reason: Original PMID:29237719 Results report CBLB coimmunoprecipitation with FLAG-tagged human CBL constructs in HEK293T cells, with wild-type and RING-mutant comparisons. This supports association in the complex, not necessarily a purified binary heterodimer or identical functions of the two ligases.

Reason: Original PMID:29237719 Results include FLAG–IFT20 affinity isolation and reciprocal endogenous coimmunoprecipitation with CBL in HEK293T cells. Only a fraction of IFT20 is associated with CBL; this does not establish that CBL is a constitutive component of every IFT-B complex or that the interaction is a purified binary contact.

Reason: PMID:19546888 tests camptothecin-treated rat neuronal cells, including combined Cbl/Cbl-b knockdown that sensitizes PC12 cells to death. Human-cell knockdown and human c-Cbl construct experiments place a suppressive action at MLK-to-MKK/JNK signaling, although the precise noncatalytic interaction mechanism remains unresolved. The DNA-damage experiment is not merely a measurement of Cbl disappearance, but the double-knockdown result does not isolate CBL from CBLB. Retain the broad transferred response as non-core with these model and redundancy limits, without assigning CBL a DNA-repair enzyme activity.

GO:0008584 male gonad development
IEA
GO_REF:0000107
UNDECIDED
Summary: Male gonad development remains a narrower unresolved claim than the established testicular phenotype.
Reason: The prior claim that Cbl-null mice are fertile and lack a gonadal phenotype is contradicted by PMID:16301331: the paper reports disrupted seminiferous germ-cell organization, loss of postmeiotic cells and predominantly male hypofertility. However, GO:0008584 concerns progression of the male gonad to its mature structure. The inspected experiments principally resolve adult germ-cell homeostasis and androgen-dependent apoptosis; an earlier developmental apoptotic defect is proposed in the Discussion as ongoing work. The precise developmental step behind this rat-to-human assertion remains unresolved. Preserve the source and positive testicular evidence without equating adult hypofertility with a demonstrated human gonad-development mechanism.

GO:0010332 response to gamma radiation
IEA

MARK AS OVER ANNOTATED
Summary: The traced irradiation readout overextends the demonstrated role of CBL.
Reason: The dated official comparative graph links the rat gamma-radiation IEP annotation to PMID:16301331. In that source, localized irradiation removes successive germ-cell populations so that changing Cbl abundance can identify the cells that normally express it. The authors explicitly consider loss of spermatocytes and altered expression as explanations. These experiments do not resolve a CBL activity executing the gamma-radiation response; CBL is measured as a marker in a cell-depletion experiment. Transferring this readout as the human process assertion overstates the demonstrated role. This conclusion follows the actual assay, not the IEP code alone, and does not imply that CBL cannot modulate other DNA-damage or apoptotic responses.

Reason: PMID:16301331 combines rat flutamide, hypophysectomy/testosterone replacement and Sertoli-cell/germ-cell cocultures with Cbl-null mouse tests. Hormonal manipulation changes Cbl expression, but the knockout experiments additionally alter androgen-dependent germ-cell apoptosis and downstream protein balance. Thus a functional Cbl contribution is supported beyond expression alone. The germ-cell response is mediated through its cellular environment rather than demonstrated direct androgen-receptor binding by CBL; no direct Bim or Smac ubiquitination was detected in these testicular assays. Retain the broad response as non-core, with rodent physiology and untested human gonadal context explicit.

Reason: PMID:19546888 provides positive c-Cbl protection against MLK-driven death in rat PC12 cells, including a RING-defective construct, and human-cell evidence that c-Cbl suppresses signaling between MLKs and MKK4/7. Cbl-b does not reproduce every c-Cbl overexpression result, and double knockdown contributes to the broader neuronal sensitization experiments. The precise protective interaction mechanism is unresolved and is not assumed to be E3-mediated destruction of MLK3.

Reason: Selected original PMID:18070883 Results and controls in human SW13 cells show SPRY2 supporting serum-dependent survival by restraining CBL-mediated receptor downregulation; dominant inhibitory CBL-TKB preserves survival after SPRY2 depletion. That is a source-specific scope/direction problem for assigning the anti-apoptotic action to active CBL. It does not establish that CBL can never support survival in other contexts.

Summary: Retain context-dependent positive EGFR regulation through the curated CBL autoubiquitination step as non-core.
Reason: The complete human Reactome pathway and its specific reactions distinguish PTK6-mediated phosphorylation of CBL (R-HSA-8848818) from CBL autoubiquitination (R-HSA-8848829), which promotes CBL degradation and attenuates receptor downregulation. CBL performs the ubiquitin-transfer step itself in the latter event, rather than serving only as an inhibited substrate. This supports the existing TAS process as a context-dependent, non-core role without reversing its usual negative receptor-regulatory function. The underlying primary full text was not inspected; this decision defers to the explicit curated human reaction, not to a pathway-title inference.

CBL/CBLB redundancy and the cell-derived-substrate reconstitution limit are preserved. Other detected linkages are not treated as equally established.

ACCEPT
Summary: Retain the electronic K63-linked ubiquitination activity.
Reason: The original human LAG3 study independently supports K63-linked chain formation by the CBL-family mechanism. Retain that target basis without pretending that the individual ARBA rule or an additional EGFR chain-topology experiment was inspected.

UNDECIDED
Summary: The hypoxia-response transfer remains source-limited.
Reason: The exact rat/Ensembl source is preserved. The underlying intervention and CBL-specific functional response were not independently resolved; an oxygen/glucose-deprivation lead is not automatically equivalent to an isolated hypoxia experiment. No expression-only or biological-absence inference is made.

KEEP AS NON CORE
Summary: Retain CBL participation in a contextual NGF response.
Reason: PMID:19546888 includes NGF withdrawal/readdition conditions, Cbl phosphorylation and loss, knockdown sensitization and c-Cbl-dependent suppression of MLK death signaling; its human constructs and human biochemical cell context are distinguished from rat neuronal survival assays. Independent PMID:21570973 supports CBL regulation of ligand-activated TrkA in its own model. These studies need not imply identical receptor downregulation in every neuronal context, and the 2009 study specifically treats the survival brake as distinct from assuming universal TrkA degradation. Retain the broad response as non-core without assigning NGF binding to CBL.

GO:1990782 protein tyrosine kinase binding
IEA
GO_REF:0000107
ACCEPT
Summary: Retain protein-tyrosine-kinase binding.
Reason: Direct CBL recognition and association studies support receptor and non-receptor tyrosine-kinase partners. The exact rat transfer is preserved; this MF neither confers kinase catalysis on CBL nor implies identical binding mechanisms for every kinase.

IEA
GO_REF:0000107
ACCEPT
Summary: Retain regulation of PDGFRA signaling.
Reason: The inspected IFT20 study combines human CBL constructs and association assays with murine ciliary feedback experiments; CBL and CBLB can act redundantly. Independent human mesenchymal-cell receptor-ubiquitination evidence supports transfer of the qualitative regulatory function. No claim is made that endogenous human PDGFRA regulation invariably requires cilia or CBL alone.

FRS2 alpha attenuates FGF receptor signaling by Grb2-mediate...
NEW
Summary: Retain the genuine historical FGFR-downregulation proposal with a revised evidence basis.
Reason: This record was already authored as NEW in the immutable prior main review; it is not a new assertion added in this revision. CBL performs the attenuating E3 step in the FRS2–GRB2 receptor complex, supported by the original recruitment/ubiquitination work and human FGFR2 evidence. The term’s parents describe negative signaling regulation, consistent with that work. The old comparison to SPRY/SULF proteins did not establish the same E3 role and is not retained as a gap argument; current same-role annotation coverage remains unresolved. Existing target GO-CAM models concern LAG3, not FGFR. Preserve the historical proposal and raise its comparator/coverage question without manufacturing another process assertion.

Core Functions

CBL recruits an E2 through its RING domain and promotes ubiquitin transfer to selected receptor and signaling substrates. This activity helps attenuate receptor signaling and directs endocytic sorting; CBL is an E3 rather than an E2 or a HECT-type thioester enzyme. In the LAG3 context, CBL and CBLB can redundantly assemble K63-linked chains that alter signaling-tail membrane association without measurably shortening LAG3 half-life. Substrate fate is therefore context dependent. In human osteoblasts, FGFR2 recruits CBL to plasma-membrane raft microdomains where increased CBL–PI3K association accompanies PI3K ubiquitination and degradation; this is a defined signaling context, not a universal location for every substrate.

Supporting Evidence:

The TKB module recognizes selected phosphorylated tyrosine motifs on kinases and regulatory proteins, positioning CBL in substrate or regulatory complexes. Structures and binding measurements establish this recognition independently of whether each intact partner is ultimately ubiquitinated. Positive partner motifs are not generalized to the wild-type FLT1 peptide that failed binding in the tested assay.

Supporting Evidence:

CBL supplies proline-rich recognition sequences that engage SH3 domains in recruitment and trafficking adaptors, including CIN85, intersectin and GRB2 in the demonstrated recruitment contexts. This interaction module links CBL to signaling and endocytic complexes. It is CBL binding a domain on its partner; phosphorylation of CBL and recruitment of a phosphotyrosine-binding partner are separate mechanisms.

Suggested Questions for Experts

Q: What original reference and assay underlie the CBL–INPPL1 binding row carrying PMID:5668240? The cached record is a peracetic-acid paper; no replacement identifier has been verified.

Q: Does the FLT1 binding annotation in PMID:18273061 refer to the engineered phosphopeptide or another assay, given the reported absence of wild-type peptide binding in that experiment?

Q: How should GO:0050821 protein stabilization apply to CBL-dependent LAG3 tail conformation? The primary study finds no increased LAG3 half-life, but the definition also refers to structural integrity and existing LAG3 GO-CAMs explicitly model stabilization; that correspondence remains unresolved.

Q: What direct human source evidence resolves the rat-derived gonad-development, hypoxia, starvation and other contextual response assertions, separating an executed CBL role from cell-composition changes or expression alone?

Q: Which assay supports CBL membership in the flotillin complex rather than transient association, and what evidence identifies CBL itself in the E-cadherin proteomics row?

Q: What same-role E3 comparator coverage best evaluates the genuine historical GO:0040037 FGFR-downregulation proposal? Existing target GO-CAMs represent LAG3 rather than FGFR; no new process assertion is added here.

Q: Which molecular interaction explains RING-independent CBL suppression of MLK-to-MKK signaling, and how does this protective context coexist with pro-apoptotic CBL effects in other cells?

Q: Which GRB2 domains or indirect complexes account for the CBL interactions in the unresolved original screening contexts, especially the phosphorylation-dependent network? Demonstrated SH3-mediated recruitment is not assumed to explain every GRB2 association.

Suggested Experiments

Experiment: In CBL-knockout (and CBL/CBLB double-knockout) human fibroblasts, re-express wild-type, RING-dead (C381A) or TKB-dead (G306E) CBL; measure FGF2-induced FGFR1/FRS2alpha ubiquitination, FGFR1 internalisation and degradation, and pERK kinetics.

Hypothesis: CBL ubiquitinates FGFR1 and FRS2alpha in human cells and this ubiquitination limits FGF-induced ERK duration.

Type: Genetic knockout and rescue with domain mutants

Experiment: Compare FGFR ubiquitination in cells expressing FRS2alpha with GRB2-binding tyrosines mutated versus FGFR with candidate TKB-binding sites mutated.

Hypothesis: GRB2-mediated recruitment through FRS2alpha, not direct TKB binding, is the dominant route for CBL to FGFRs.

Type: Site-directed mutagenesis and ubiquitination assays
