Comments
Mutations of PINK1 causes Parkinson’d Disease. PINK1 is imported into the mitochondria, cleaved by the PARL protein between residues 103 and 104, and released back into the cytoplasm. Cleaved mature PINK1 (ΔM104PINK1) then resides in the cytoplasm. It enhances formation of aggregasomes and autophagy, thus important for stress-induced proteasome-mediated cell death. Upon proteasome dysfunction, PINK1 is mono-ubiquitinated and goes into the nucleus. When treated with MG132, M104PINK1 aggregates in the cytoplasm and a fraction enters the nucleus, and LMB increases nuclear PINK1 in cells treated with MG132. An NES was identified at the C-terminus of PINK1. Using NES consensus sequences, the authors found a match between residues 510-524, which is conserved in several species. WT NES and NES mutant L511/L517 are cytoplasmic, but LMB caused them to be in the nucleus. NES mutant L511/L517/L522/L534 is in the nucleus. An NLS-mCherry-NES is both in the nucleus and the cytoplasm but LMB caused it to be nuclear.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
