Summary
Enables ubiquitin binding activity. Involved in several processes, including ATP export; protein targeting; and reticulophagy. Located in cytoplasmic side of plasma membrane and endosome. Part of ESCRT I complex. Human ortholog(s) of this gene implicated in breast cancer; breast carcinoma; cervix carcinoma; endometrial adenocarcinoma; and prostate cancer. Orthologous to several human genes including TSG101 (tumor susceptibility 101). [provided by Alliance of Genome Resources, Nov 2024]

  • 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
