Swiss-port # O60260 Human E3 ubiquitin-protein ligase parkin |
|---|---|
| Gene Symbol | PARK2 |
| Gene Full Name | parkin RBR E3 ubiquitin protein ligase |
| Background | Parkin is an E3 ligase in the ubiquitin-proteasome system. Hereditary Parkinson’s disease is most commonly caused by mutations in the parkin gene and is characterized by the progressive loss of dopaminergic neurons and the presence of Lewy bodies in the substania nigra (Jenner et al.,1992). Recent evidence suggests that phosphorylation of parkin at Ser378 may have an important regulatory role on its E3 ubiquitin ligase activity (Yamamoto et al., 2005). |
| Research Area | Cell Biology and Cellular Response antibody; Metabolism antibody; Neuroscience antibody |
| Calculated MW | 52 kDa |
| PTM | Auto-ubiquitinates in an E2-dependent manner leading to its own degradation (PubMed:19229105). Also polyubiquitinated by RNF41 for proteasomal degradation. S-nitrosylated. The inhibition of PRKN ubiquitin E3 ligase activity by S-nitrosylation could contribute to the degenerative process in PD by impairing the ubiquitination of PRKN substrates. Phosphorylation at Ser-65 by PINK1 contributes to activate PRKN activity. It is however not sufficient and requires binding to phosphorylated ubiquitin as well. |
