Ubiquitin Specific Peptidase 8 (
USP
8), also known as ubiquitin isopeptidase Y (UBPY), is a widely expressed deubiquitinating enzyme belonging to the peptidase C19 family. It has a predicted molecular weight of 127.5 kDa. Human
USP
8 is 1118 amino acids (aa) in length and shares 84% aa sequence identity with the mouse and rat orthologs. It contains a N-terminal MIT domain (aa 33-116) that mediates endosomal localization, CHMP-binding, and maintenance of ESCRT-0.
USP
8 also has a rhodanese domain (aa 181-319) that binds NRDP1 ubiquitin ligase (E3), a SH3 domain binding sequence (aa 405-413), and a C-terminal catalytic domain (aa 734-1110).
USP
8 is a growth-regulated enzyme that controls the internalization and endocytic trafficking of cell surface receptors. Some receptors are targeted for internalization and degradation by ubiquitination.
USP
8 has been shown to disrupt the down-regulation of multiple receptors, including EGF R/ErbB1, ErbB2/Her2 and Smoothened, via their deubiquitination. Conversely,
USP
8 appears to have the opposite effect on the trafficking of CXCR4, PAR2, and the δ-opioid receptor. Depletion or catalytic inactivation of

lized their expression. It is thought that deubiquitination of these receptors down-stream of the sorting endosome commits them to lysosomal degradation.
USP
8 can be phosphorylated at Ser680 allowing for 14-3-3-epsilon binding, which subsequently inhibits
USP
8 activity. Additionally,
USP
8 undergoes tyrosine phosphorylation at its N-terminus following EGF activation of the EGFR/ErbB1/ErbB2/Her2 receptor complex.
