About TAP2

Summary

Enables several functions, including TAP binding activity; adenyl ribonucleotide binding activity; and protein homodimerization activity. Contributes to MHC class I protein binding activity and peptide antigen binding activity. Involved in several processes, including peptide transport; positive regulation of antigen processing and presentation of peptide antigen via MHC class I; and protection from natural killer cell mediated cytotoxicity. Acts upstream of or within antigen processing and presentation of endogenous peptide antigen via MHC class I and positive regulation of T cell mediated cytotoxicity. Located in intracellular membrane-bounded organelle. Part of TAP complex. Human ortholog(s) of this gene implicated in several diseases, including MHC class I deficiency; aspirin-induced respiratory disease; autoimmune disease (multiple); cervical Cancer (multiple); and systemic scleroderma (multiple). Orthologous to human TAP2 (transporter 2, ATP binding cassette subfamily B member). [provided by Alliance of Genome Resources, Apr 2022]
