>gnl|CDD|73007 cd03248, ABCC_TAP, TAP, the Transporter Associated with Antigen Processing; TAP is essential for peptide delivery from the cytosol into the lumen of the endoplasmic reticulum (ER), where these peptides are loaded on major histocompatibility complex (MHC) I molecules. Loaded MHC I leave the ER and display their antigenic cargo on the cell surface to cytotoxic T cells. Subsequently, virus-infected or malignantly transformed cells can be eliminated. TAP belongs to the large family of ATP-binding cassette (ABC) transporters, which translocate a vast variety of solutes across membranes.. Length = 226
