Parkin (human) polyclonal antibody

Parkin is a ubiquitin-protein ligase (E3), and mutations in the Parkin gene appear to be closely associated with autosomal recessive juvenile Parkinson’s disease. Parkin has been localised to Lewy bodies in patients with sporadic Parkinson’s disease, and in peri-nuclear aggresome-like inclusions in cells over-expressing wild-type Parkin where proteasomal activity has also been inhibited⁴. Both types of inclusion also contain ubiquitin, α-synuclein, proteasomal subunits and heat shock proteins. A recent paper suggests that loss of proteasomal activity leads to Parkin accumulation with a concomitant reduction in E3 ligase activity resulting in Lewy body formation⁵.Parkin is selectively recruited from the cytosol to damaged mitochondria to trigger their autophagy (mitophagy).
