Function: Involved in the association of MHC class I with transporter associated with antigen processing (TAP) and in the assembly of MHC class I with peptide (peptide loading).
Cellular location: Endoplasmic reticulum membrane; Single-pass type I membrane protein (Probable).
Tissue specificity: Neutrophils, mostly in fully differentiated cells.

Genetic variants

The 2 alleles of TAPBP; TAPBP*01 (Tapasin*01) (shown here) and TAPBP*02 (Tapasin*02); are in linkage disequilibria with the HLA-DRB1 locus in a Japanese population.
