Automated description from the Alliance of Genome Resources (Release 3.0)
Predicted to have TAP complex binding activity; TAP1 binding activity; and TAP2 binding activity. Involved in antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-dependent; defense response; and peptide antigen stabilization. Predicted to localize to Golgi membrane and MHC class I peptide loading complex. Human ortholog(s) of this gene implicated in MHC class I deficiency and severe combined immunodeficiency. Is expressed in several structures, including genitourinary system; hemolymphoid system; nervous system; notochord; and retina. Orthologous to human TAPBP (TAP binding protein).
