Web13 Mar 2024 · Parkin is an E3 ubiquitin ligase that contains a ubiquitin-like domain and four RING domains: RING0, RING1, IBR, and RING2 [ 62 ]. Its basal activity is minimal due to intramolecular interactions that block the active site and compete with E2 ligase binding [ 57 ]. Upon mitochondrial injury, PINK1 activates Parkin through two mechanisms. WebPINK1 directly phosphorylates Parkin at a highly conserved serine 65 (Ser65) residue within its N-terminal ubiquitin-like domain (Ubl), as well as the equivalent Ser65 residue of ubiquitin (Ub). Phosphorylation of both Parkin and ubiquitin is required for maximal activation of Parkin E3 ligase activity [ 7 – 11 ].

WebParkin is an enzyme commonly defective in inherited forms of Parkinson’s disease. To maintain cellular health, Parkin attaches a small protein to damaged mitochondria, marking them for degradation. Although stabilising the active form of Parkin could form the basis of therapy, this state has evaded structural characterisation.
