Tsg101 Gene Summary [Rat]
Predicted to enable several functions, including protein homodimerization activity; ubiquitin protein ligase binding activity; and virion binding activity. Involved in endosome to lysosome transport; positive regulation of DNA-templated transcription; and positive regulation of protein monoubiquitination. Located in endosome membrane and nucleus. Human ortholog(s) of this gene implicated in breast cancer; breast carcinoma; cervix carcinoma; endometrial adenocarcinoma; and prostate cancer. Orthologous to human TSG101 (tumor susceptibility 101). [provided by Alliance of Genome Resources, Jul 2025]
