WebMar 23, 2011 · We have performed a gain- and loss-of-function approach, demonstrating that human Pink1 is cleaved by PARL. This cleavage is dependent on an intact mitochondrial membrane potential and can be blocked by mutations in the Pink1 TMD, including at least one that causes early-onset PD. WebPINK1 is translated in the cytosol, then translocated to the outer mitochondrial membrane where it is rapidly cleaved and degraded as a part of normal mitochondrial function. In damaged (depolarized) mitochondria, PINK1 becomes stabilized and accumulates, resulting in the subsequent phosphorylation of numerous proteins on the mitochondrial surface.

WebDec 6, 2010 · PINK1 cleavage occurs within mitochondria ( 15) and is dependent on mitochondrial integrity ( 10, 11, 16 ). However, investigations to determine the biological significance of the full-length and PINK1 cleavage products have been significantly hindered because the cleavage site of PINK1 was unknown. WebWhen mitochondria are damaged, molecules such as PINK1 accumulate on the surface, alerting the cell to consume the misbehaving organelle. Clearing nonfunctional mitochondria staves off cell death. Healthy mitochondria import PINK1, cleave it, and release the shortened protein. Shortened PINK1 signals the growth of long and elaborate dendrites.
