单词 | park2 |
释义 | PARK2PARK2A gene on chromosome 6q25.2-q27 that encodes a protein that functions within a multiprotein E3 ubiquitin ligase complex, catalysing the covalent attachment of ubiquitin moieties onto substrate proteins—e.g., BCL2, SYT11, CCNE1, GPR37, STUB1, SEPT5, ZNF746 and AIMP2. It also participates in the removal and/or detoxification of abnormally folded or damaged protein by mediating polyubiquitination of misfolded proteins. PARK2 may play a role in controlling neurotransmitter trafficking at the presynaptic terminal and in calcium-dependent exocytosis; it may have tumour suppressor activity. |
