Tapasin, or TAPBP (MIM 601962), is a member of the variable-constant Ig superfamily that links major histocompatibility complex (MHC) class I molecules to the transporter associated with antigen processing (TAP; see MIM 170260) in the endoplasmic reticulum (ER). The TAPBP gene is located near the MHC complex on chromosome 6p21.3. TAPBPL is a member of the Ig superfamily that is localized on chromosome 12p13.3, a region somewhat paralogous to the MHC.
Predicted location

Intracellular, Membrane (different isoforms)

Single cell type specificity

Cell type enhanced (Plasma cells, Proximal enterocytes)

Immune cell specificity

Low immune cell specificity

Cell line specificity

Cell line enhanced (CAPAN-2, HDLM-2, Karpas-707, RPMI-8226)

Interaction

Interacts with peptide-free HLA-A*02-B2M complexes or those loaded with low affinity peptides, likely facilitating peptide exchange onto higher affinity peptides.
