About TAP2

Cytogenetic location: 6p21.32 Genomic coordinates (GRCh38): 6:32,821,831-32,838,739 (from NCBI)

This gene has 9 transcripts (splice variants), 1 gene allele, 159 orthologues, 10 paralogues and is associated with 2 phenotypes. Ubiquitous expression in appendix (RPKM 22.8), lymph node (RPKM 22.1) and 24 other tissues.

Summary

The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance. This gene is located 7 kb telomeric to gene family member ABCB2. The protein encoded by this gene is involved in antigen presentation. This protein forms a heterodimer with ABCB2 in order to transport Peptides from the cytoplasm to the endoplasmic reticulum. Mutations in this gene may be associated with ankylosing spondylitis, insulin-dependent diabetes mellitus, and celiac disease. Alternative splicing of this gene produces products which differ in peptide selectivity and level of restoration of surface expression of MHC class I molecules. [provided by RefSeq, Feb 2014]
