  • 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.
  • Involvement in disease

    Bare lymphocyte syndrome 1
  • Sequence similarities

    Belongs to the ABC transporter superfamily. ABCB family. MHC peptide exporter (TC 3.A.1.209) subfamily.
    Contains 1 ABC transmembrane type-1 domain.
    Contains 1 ABC transporter domain.
  • Domain

    The peptide-binding site is shared between the cytoplasmic loops of TAP1 and TAP2.
  • Cellular localization

    Endoplasmic reticulum membrane. The transmembrane segments seem to form a pore in the membrane.
