Gene: Tap2 (transporter 2, ATP-binding cassette, sub-family B (MDR/TAP)) Mus musculus
Symbol: Tap2
Name: transporter 2, ATP-binding cassette, sub-family B (MDR/TAP)
Description: Exhibits TAP1 binding activity. Predicted to contribute to peptide antigen binding activity and peptide transmembrane transporter activity. Involved in 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 localize to the TAP complex and nuclear speck. Human ortholog(s) of this gene implicated in several diseases, including MHC class I deficiency; autoimmune hypersensitivity disease (multiple); bone inflammation disease (multiple); cervical cancer (multiple); and dengue hemorrhagic fever. Is expressed in hemolymphoid system and thymus primordium. Orthologous to human TAP2 (transporter 2, ATP binding cassette subfamily B member).
Type: protein-coding
RefSeq Status: REVIEWED
