An ATP-binding cassette, sub-family B protein (ATP BINDING CASSETTE TRANSPORTER, SUBFAMILY B) that functions in the transport of ANTIGENS from the CYTOPLASM to the ENDOPLASMIC RETICULUM for association with HISTOCOMPATIBILITY ANTIGENS CLASS I peptides. It also acts as a molecular scaffold for the final stage of MHC class I PROTEIN FOLDING.
