  • Gene name:
    TAP2(ABCB3;PSF2;RING11;Y1);
    Protein name:
    Antigen peptide transporter 2(APT2);
    Alternative:
    Peptide supply factor 2;ATP-binding cassette sub-family B member 3;Peptide transporter TAP2;Peptide transporter PSF2(PSF-2);Really interesting new gene 11 protein;Peptide transporter involved in antigen processing 2;
    Organism:
    Human (Homo sapiens). 
    General Annotation
    Sub Unit:
    Heterodimer of TAP1 and TAP2. Interacts with Epstein-Barr virus BLNF2a.
    Function:
    Involved in the transport of antigens from the cytoplasm to the endoplasmic reticulum for association with MHC class I molecules. Also acts as a molecular scaffold for the final stage of MHC class I folding, namely the binding of peptide. Nascent MHC class I molecules associate with TAP via tapasin. Inhibited by the covalent attachment of herpes simplex virus ICP47 protein, which blocks the peptide-binding site of TAP. Inhibited by human cytomegalovirus US6 glycoprotein, which binds to the lumenal side of the TAP complex and inhibits peptide translocation by specifically blocking ATP-binding to TAP1 and prevents the conformational rearrangement of TAP induced by peptide binding. Inhibited by human adenovirus E3-19K glycoprotein, which binds the TAP complex and acts as a tapasin inhibitor, preventing MHC class I/TAP association.
    Subcellular Location:
    Endoplasmic reticulum membrane Multi-pass membrane protein The transmembrane segments seem to form a pore in the membrane.
