Parkin activity

Web20 Mar 2024 · Autosomal recessive mutations in the Parkin gene cause Parkinson’s disease. Parkin encodes an ubiquitin E3 ligase that functions together with the kinase PINK1 in a mitochondrial quality control pathway. Parkin exists in an inactive conformation mediated by autoinhibitory domain interfaces. Thus, Parkin has become a target for the development … Web17 Apr 2024 · These findings suggest a role for ubiquitin (or ubiquitin-like protein) binding at surfaces exposed upon pUb binding in the regulation of Parkin activity. Consistent with this, a recent study shows that modification of the IBR domain at Lys349 and Lys369 by the ubiquitin-like protein ISG15, positively regulates Parkin activity 48.
