Parkin mitochondrial translocation
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. Web1 Nov 2024 · Thus, the protein import process is not only essential for the translocation of nuclear-derived proteins into the organelle, it also serves to match the health status of the organelle to the appropriate signalling response in order to maintain an optimal mitochondrial pool. ... by promoting Parkin localization to mitochondria as well as an ...

Web9 Nov 2024 · PINK1 regulates PARKIN translocation in impaired mitochondria and drives their removal via selective autophagy, a process known as mitophagy. As knowledge obtained using different PINK1 and PARKIN transgenic animal models is being gathered, growing evidence supports the contribution of mitophagy impairment to several human … 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 …
Web13 Mar 2024 · A recent study suggests that damage to axonal mitochondria in cultured neurons can induce rapid (within ~ 1 h) Parkin translocation followed by recruitment of autophagosomes and removal via lysosomes . Thus, in contrast to cell lines, variability in the intracellular environment and mitochondrial stresses of different neuronal compartments … Web9 Sep 2012 · Mitochondrial translocation of Parkin. HeLa cells expressing GFP-tagged Parkin (green) were treated with (+) or without (–) 10 μM CCCP for 3 hrs to disrupt the mitochondrial membrane potential (Δψm).Parkin was moved to mitochondria upon the reduction of Δψm (stained with mitochondrial outer membrane protein Tom20 (red), …

Web1 Oct 2024 · In 2013, an unexpected hint came from T. Hunter’s group (Zheng and Hunter, 2013), who proposed that mitochondrial translocation of phosphorylated Parkin is achieved through a novel catalytic activity coupled mechanism by binding of Parkin to the polyubiquitin chain of an OMM protein(s). However, additional tests revealed that the …
Web15 Feb 2012 · PTEN-induced kinase 1 (PINK1) and Parkin are mutated in many cases of early-onset familial Parkinson's disease (PD), but how these proteins are related to the pathogenesis of PD was unclear.
