Heterodimer of TAP1 and TAP2 (TAP1-TAP2) (PubMed:1538751). A component of the peptide loading complex (PLC), interacts via TAPBP with MHCI heterodimer; this interaction mediates peptide-MHCI assembly (PubMed:26611325). Recruits TAPBP in a 1:1 stoichiometry (PubMed:22638925). Interacts with classical MHCI such as HLA-A*02-B2M; this interaction is obligatory for the loading of peptide epitopes (PubMed:8805302, PubMed:8630735). Interacts with non-classical MHCI molecules including HLA-E-B2M and HLA-F-B2M as well as PLC component CALR before the peptide loading (PubMed:9427624, PubMed:10605026). (Microbial infection) Interacts with Epstein-Barr virus BLNF2a. (Microbial infection) Interacts with herpes simplex virus US12/ICP47. (Microbial infection) Interacts with adenovirus E3-19K glycoprotein, which binds TAP1-TAP2 and acts as a TAPBP inhibitor, preventing TAP1-TAP2 association with MHCI.
