Western Blot: UBPY/USP8 Antibody [NBP1-50001]

Western Blot: UBPY/USP8 Antibody [NBP1-50001] - Detection of Human USP8 by Western Blot and Immunoprecipitation. Samples: Whole cell lysate from HeLa (5, 15 and 50 mcg for WB; 1 mg for IP, 20% of IP loaded) and 293T (T; 50 mcg) cells. Antibodies: Affinity purified rabbit anti-USP8 antibody used for WB at 0.04 mcg/ml (A) and 0.4 mcg/ml (B) and used for IP at 3 mcg/mg lysate. USP8 was also immunoprecipitated by rabbit anti-USP8 antibody which recognizes a downstream epitope. For blotting immunoprecipitated USP8, the ReliaBLOT(R) Reagents and Procedures were used. Detection: Chemiluminescence with exposure times of 3 minutes (A) and 10 seconds (B).

Background: USP8

Ubiquitin Specific Peptidase 8 (USP8), 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 USP8 is 1118 amino acids (aa) in length and shares 84% aa sequence identity with the mouse and rat orthologs. It contains an N-terminal MIT domain (aa 33-116) that mediates endosomal localization, CHMP-binding, and maintenance of ESCRT-0. USP8 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). USP8 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. USP8 has been shown to disrupt the down-regulation of multiple receptors, including EGF R/ErbB1, ErbB2/Her2, and Smoothened, via their deubiquitination. Conversely, USP8 appears to have the opposite effect on the trafficking of CXCR4, PAR2, and the delta-opioid receptor. Depletion or catalytic inactivation of USP8 stabilized their expression. It is thought that deubiquitination of these receptors down-stream of the sorting endosome commits them to lysosomal degradation. USP8 can be phosphorylated at Ser680 allowing for 14-3-3-epsilon binding, which subsequently inhibits USP8 activity. Additionally, USP8 undergoes tyrosine phosphorylation at its N-terminus following EGF activation of the EGF R/ErbB1 / ErbB2/Her2 receptor complex.
