STP22/YCL008C Summary Help

Standard Name STP22 1
Systematic Name YCL008C
Alias VPS23 2 , 3 , VPL15 3 , AGS1 4
Feature Type ORF, Verified
Description Component of the ESCRT-I complex; ESCRT-I is involved in ubiquitin-dependent sorting of proteins into the endosome; prevents polyubiquitination of the arrestin-related protein Rim8p, thereby directing its monoubiquitination by Rsp5p; homologous to the mouse and human Tsg101 tumor susceptibility gene; mutants exhibit a Class E Vps phenotype; (5, 6, 7)
Name Description STerile Pseudoreversion 1
