PRKN activates UCHL1. 4 / 4
| 4

reach
"Our data showed that phospho-pink1 and parkin, two key regulators of mitophagy, have upregulated protein expression in UCHL1 smKO mice at day 7."

reach
"Taken together, these results suggest that loss of parkin mediated UCH-L1 regulation may be a pathogenic mechanism contributing to neurodegeneration in human ARJP patients with parkin mutations."

reach
"The parkin induced UCH-L1 degradation was blocked by the lysosome inhibitor chloroquine (CQ) or the autophagy inhibitor 3MA but not by the proteasome inhibitor MG132 (XREF_FIG)."

reach
"Consistent with the accelerated UCH-L1 turnover rate induced by parkin overexpression, the steady-state level of endogenous UCH-L1 protein was significantly lower in parkin WT overexpressing SH-SY5Y cells than that in the vector transfected control cells (XREF_FIG)."
