General description

Tumor susceptibility 101 (TSG101) is encoded by the gene mapped to human chromosome 11p15.1–15.2. The encoded protein is a member of catalytically inactive ubiquitin E2 variant (UEV) family. Tsg101 is characterized with an ubiquitin E2 variant (UEV) domain in its N-terminal end involved in HIV-1 budding and the vacuolar protein sorting (VPS) pathway.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium axide.


Anti-TSG101 antibody produced in rabbit has been used for western blotting.

Biochem/physiol Actions

Tumor susceptibility 101 (TSG101) is implicated in various cellular function such as, ubiquitination, transcriptional regulation, endosomal trafficking and cell proliferation. Mutation in the gene leads to various human cancers.Tsg101 plays a crucial role in cell growth, cell survival, and normal function of embryonic and adult tissues. TSG101 facilitates infectious human immunodeficiency virus (HIV-1) budding by linking the p6 late domain to vacuolar protein sorting machinery. Tsg101 is a vital constituent of the endosomal sorting complex required for transport (ESCRT) machinery, that helps in synthesis of multi-vesicular bodies, mainly the formation and scission of the intraluminal vesicles, and is thus, crucial for the degradation and recycling of receptors localized on plasma membrane. Tsg101 expression is controlled by an intrinsic autoregulatory mechanism and by ubiquitination catalyzed by various ubiquitin ligases.
