Gene Description

PRKN (Parkin, PARK2) is a 465-residue RING-between-RING (RBR) E3 ubiquitin ligase. Mutations in PRKN are the most common cause of autosomal recessive juvenile parkinsonism. Parkin has an N-terminal ubiquitin-like (Ubl) domain and four zinc-coordinating domains (RING0, RING1, IBR, RING2). It works as a RING/HECT hybrid: RING1 binds the E2~ubiquitin conjugate (UbcH7/UBE2L3), and ubiquitin is transferred via a thioester intermediate on the catalytic Cys431 in RING2. In resting cells Parkin is cytosolic and autoinhibited: the Ubl and RING0 domains occlude the E2-binding site and the catalytic cysteine. On damaged, depolarized mitochondria, PINK1 accumulates on the outer membrane and phosphorylates ubiquitin at Ser65. Phospho-ubiquitin recruits Parkin and promotes PINK1 phosphorylation of Ser65 in the Parkin Ubl, which fully releases autoinhibition. Activated Parkin ubiquitinates many outer-membrane proteins (mitofusins, Miro, VDAC1, TOM subunits), forming K6, K11, K48 and K63 chains. These chains are further phosphorylated by PINK1 in a feed-forward loop. The phospho-ubiquitin coat recruits autophagy receptors and drives mitophagy, while proteasomal degradation of mitofusins and Miro isolates and immobilizes the damaged organelle. USP30 and other deubiquitinases oppose Parkin action. Parkin also ubiquitinates many cytosolic and ER-associated substrates (e.g. Pael-R, PARIS/ZNF746, synphilin-1, Fbw7beta, RIPK3, NEMO), and these activities underlie reported roles in protection against unfolded-protein and oxidative stress, NF-kappaB signalling, necroptosis and synaptic function.

Summary: Parkin protects against oxidative stress.
Reason: Parkin has many reported neuroprotective, anti-apoptotic and substrate-specific roles in neurons. Most are linked to its E3 ligase activity on individual substrates.

GO:0016579 protein deubiquitination
TAS
Reactome:R-HSA-5688426

Summary: Reactome places Parkin in the "deubiquitination" pathway because it is a substrate of DUBs (e.g. USP8, USP30 counteract it).
Reason: Parkin is an E3 ligase and does not carry out deubiquitination. Pathway membership as a DUB substrate is not participation in the process.
Supporting Evidence:
PMID:25621951
We find that mitochondrial damage stimulates parkin to assemble Lys 6, Lys 11 and Lys 63 chains on mitochondria, and that USP30 is a ubiquitin-specific deubiquitylase with a strong preference for cleaving Lys 6- and Lys 11-linked multimers.

KEEP AS NON CORE
Summary: Parkin promotes K63 and linear ubiquitination of NEMO/TRAF2 and activates canonical NF-kappaB signalling.
Reason: Parkin has many reported neuroprotective, anti-apoptotic and substrate-specific roles in neurons. Most are linked to its E3 ligase activity on individual substrates. They are genuine but secondary to its core, conserved role as the PINK1-activated E3 ligase for mitochondrial quality control.
Supporting Evidence:
PMID:17314283
Finally, we present evidence that parkin interacts with and promotes degradation-independent ubiquitylation of IKKgamma/NEMO (NF-kappaB essential modifier) and TRAF2 [TNF (tumor necrosis factor) receptor-associated factor 2], two critical components of the NF-kappaB pathway.
PMID:23453807
Under cellular stress, parkin is recruited to the linear ubiquitin assembly complex and increases linear ubiquitination of NF-ΞΊB essential modulator (NEMO), which is essential for canonical NF-ΞΊB signaling.

PMID:24784582
Ubiquitin is phosphorylated by PINK1 to activate parkin.
ACCEPT
Summary: Parkin binds Ser65-phosphorylated ubiquitin, which recruits it to mitochondria and allosterically activates it.
Reason: Phospho-ubiquitin binding is a central part of the Parkin activation mechanism.
Supporting Evidence:
PMID:24784582
PINK1 is a Ser/Thr kinase that specifically accumulates on depolarized mitochondria, whereas parkin is an E3 ubiquitin ligase that catalyses ubiquitin transfer to mitochondrial substrates.
PMID:24660806
We undertook a series of experiments that provide striking evidence that Ser65-phosphorylated ubiquitin (ubiquitinPhospho-Ser65) functions as a critical activator of Parkin.

UNDECIDED
Summary: HCV core protein binds Parkin and suppresses Parkin-mediated mitophagy. Silencing Parkin reduced HCV core expression, implying that Parkin supports rather than suppresses viral propagation.

Our findings suggest that parkin is important for aggresome formation in human neuronal cells and may lead to a better understanding of the biogenesis of LBs in sporadic PD.
PMID:15728840
In addition we found that parkin-mediated ubiquitination of proteins within Lewy-body-like inclusions formed by the coexpression of synphilin-1, alpha-synuclein, and parkin occurs predominantly via K63 linkages and that the formation of these inclusions is enhanced by K63-linked ubiquitination.

GO:1903377 negative regulation of oxidative stress-induced neuron intrinsic apoptotic signaling pathway
IEA
GO_REF:0000120
KEEP AS NON CORE
Summary: Parkin protects neurons from oxidative-stress-induced apoptosis (e.g. via NF-kappaB signalling).
Reason: Parkin has many reported neuroprotective, anti-apoptotic and substrate-specific roles in neurons. Most are linked to its E3 ligase activity on individual substrates. They are genuine but secondary to its core, conserved role as the PINK1-activated E3 ligase for mitochondrial quality control.

Summary: NAS annotation, from a study of p62-dependent mitochondrial clustering, to a term GOA labels obsolete.

Core Functions

PINK1-activated RBR E3 ubiquitin ligase for damaged mitochondria. Phospho-ubiquitin binding and Ubl Ser65 phosphorylation by PINK1 relieve autoinhibition. Parkin then binds E2~Ub through RING1 and transfers ubiquitin via catalytic Cys431 to outer-membrane proteins (mitofusins, Miro, VDAC1), building chains that mark the mitochondrion for autophagic removal.

Supporting Evidence:
  • PMID:19029340
    Here, we show that Parkin is selectively recruited to dysfunctional mitochondria with low membrane potential in mammalian cells.
  • PMID:19029340
    After recruitment, Parkin mediates the engulfment of mitochondria by autophagosomes and the selective elimination of impaired mitochondria.
  • PMID:23770887
    In cells, mutation of C431 eliminates Parkin-catalysed degradation of mitochondria, and capture of an ubiquitin oxyester confirms C431 as Parkin's cellular active site.
  • PMID:23754282
    Furthermore, formation of the ubiquitin-ester depends on PINK1 phosphorylation of Parkin Ser-65.
  • PMID:24751536
    Recombinant TcPINK1 directly phosphorylated ubiquitin and phospho-ubiquitin activated Parkin E3 ubiquitin ligase activity in cell-free assays.
  • PMID:25621951
    We find that mitochondrial damage stimulates parkin to assemble Lys 6, Lys 11 and Lys 63 chains on mitochondria, and that USP30 is a ubiquitin-specific deubiquitylase with a strong preference for cleaving Lys 6- and Lys 11-linked multimers.

Ubiquitin-dependent proteasomal degradation of substrates. Parkin ubiquitinates mitochondrial (Miro, mitofusins) and non-mitochondrial substrates (PARIS/ZNF746, Pael-R, Fbw7beta) for proteasomal turnover. This contributes to quarantine of damaged mitochondria and to neuronal survival.

Supporting Evidence:
  • PMID:22078885
    The phosphorylation of Miro activates proteasomal degradation of Miro in a Parkin-dependent manner.
  • PMID:21376232
    whose levels are regulated by the ubiquitin proteasome system via binding to and ubiquitination by the E3 ubiquitin ligase, parkin
  • PMID:11439185
    Parkin specifically ubiquitinates this receptor in the presence of ubiquitin-conjugating enzymes resident in the endoplasmic reticulum and promotes the degradation of insoluble Pael receptor, resulting in suppression of the cell death induced by Pael receptor overexpression.
  • PMID:23858059
    Specifically, parkin targets the SCF substrate adapter Fbw7Ξ² for proteasomal degradation.

Suggested Questions for Experts

Q: Which of the many reported non-mitochondrial Parkin substrates (PARIS, Pael-R, synphilin-1, Fbw7beta, RIPK3, NEMO) are physiologically relevant in human dopaminergic neurons at endogenous Parkin levels, compared with its mitophagy role?

Q: Is Parkin transcriptional repression of TP53 a genuine nuclear activity of Parkin or an indirect effect of its ligase activity?

Suggested Experiments

Experiment: Use ubiquitin-remnant (diGly) proteomics in iPSC-derived DA neurons from PRKN-null versus isogenic controls, with and without mitochondrial stress and with PINK1 knockout, to define the endogenous PINK1-dependent and PINK1-independent Parkin substrate repertoire.

Hypothesis: Endogenous Parkin activity in dopaminergic neurons in vivo is predominantly mitochondrial and PINK1-dependent.
