DESCRIPTION

Also known as TS101_HUMAN, TSG101. Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Mediates the association between the ESCRT-0 and ESCRT-I complex. Required for completion of cytokinesis; the function requires CEP55. May be involved in cell growth and differentiation. Acts as a negative growth regulator. Involved in the budding of many viruses through an interaction with viral proteins that contain a late-budding motif P-[ST]-A-P. This interaction is essential for viral particle budding of numerous retroviruses. Required for the exosomal release of SDCBP, CD63 and syndecan (PubMed:22660413). It may also play a role in the extracellular release of microvesicles that differ from the exosomes (PubMed:22315426). Component of the ESCRT-I complex (endosomal sorting complex required for transport I) which consists of TSG101, VPS28, a VPS37 protein (VPS37A to -D) and MVB12A or MVB12B in a 1:1:1:1 stoichiometry (PubMed:18005716). Interacts with VPS37A, VPS37B and VPS37C (PubMed:15218037, PubMed:15509564). Interacts with DMAP1 (PubMed:10888872). Interacts with ubiquitin (PubMed:11595185). Interacts with stathmin, GMCL and AATF (By similarity). Component of an ESCRT-I complex (endosomal sorting complex required for transport I) which consists of TSG101, VPS28, VPS37A and UBAP1 in a 1:1:1:1 stoichiometry (PubMed:21757351). Interacts with HGS; the interaction mediates the association with the ESCRT-0 complex. Interacts with GGA1 and GGA3 (PubMed:15143060, PubMed:15039775). Interacts (via UEV domain) with PDCD6IP/AIP1 (PubMed:14505570, PubMed:14519844). Interacts with VPS28, SNF8 and VPS36 (PubMed:14505570). Self-associates (PubMed:14505570, PubMed:14519844). Interacts with MVB12A; the association appears to be mediated by the TSG101-VPS37 binary subcomplex. Interacts with VPS37D. Interacts with LRSAM1. Interacts with CEP55; the interaction is required for cytokinesis but not for viral budding (PubMed:17853893). Interacts with PDCD6 (PubMed:18256029). Interacts with LITAF (PubMed:23166352). Interacts with MGRN1 (PubMed:17229889). Interacts with ARRDC1; recruits TSG101 to the plasma membrane (PubMed:21191027, PubMed:22315426).
