WebPINK1 or parkin causes an increase in Mfn abundance in vivo and concomitant elongation of mitochondria. These ﬁndings provide a molecular mechanism by which the … Web12 Apr 2024 · The cytosolic 52 kDa form accumulates when the proteasome is inhibited and may play a role in preventing parkin translocation to mitochondria (Fedorowicz et al., 2014). Thus, full-length PINK1 is associated with activation, whereas the cleaved form is unstable, which represses mitophagy.

Web3 Jul 2014 · Parkin translocation to mitochondria was followed, within 24 hr, by complete loss of multiple mitochondrial markers, such as TOM20, HSP60, COXIII, and cytochrome c (Figures 1B–1D; Figure S1A available online). In CCCP-treated cells lacking mitochondrial markers, Parkin was again found in the cytosol (Figure 1B). WebParkin is a ubiquitin E3 ligase that ubiquitinates dysfunctional proteins for their degradation in the proteasome. The loss of parkin activity leads to the accumulation of parkin substrates. ...
