Tap1 - transporter 1, ATP-binding cassette, sub-family B (MDR/TAP) Gene

Also Known as Y3; TAP; APT1; Ham1; MTP1; PSF1; ABC17; Abcb2; Ham-1; RING4; Tap-1

Species: Mus musculus

Gene Type: protein coding
Gene ID: 21354

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 protein forms a heterodimer with Tap2 that transports short peptides from the cytosol into the endoplasmic reticulum lumen. Mutations in the human gene may be associated with ankylosing spondylitis, insulin-dependent diabetes mellitus, and celiac disease. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2009]
