Automated description from the Alliance of Genome Resources (Release 7.4.0)
Enables TAP1 binding activity. Acts upstream of or within several processes, including antigen processing and presentation of endogenous peptide antigen via MHC class I via ER pathway, TAP-dependent; antigen processing and presentation of endogenous peptide antigen via MHC class Ib via ER pathway, TAP-dependent; and antigen processing and presentation of exogenous protein antigen via MHC class Ib, TAP-dependent. Predicted to be located in endoplasmic reticulum membrane and nuclear speck. Predicted to be part of TAP complex. Predicted to be active in endoplasmic reticulum and membrane. Is expressed in hemolymphoid system and thymus primordium. Human ortholog(s) of this gene implicated in several diseases, including aspirin-induced respiratory disease; autoimmune disease (multiple); cervical cancer (multiple); dengue hemorrhagic fever; and systemic scleroderma (multiple). Orthologous to human TAP2 (transporter 2, ATP binding cassette subfamily B member).
