Gene Information

human ... TAP1(6890)

General description

The transporter protein associated with antigen processing-1 (TAP1) belongs to the major histocompatibility complex (MHC) class I peptide-loading complex. TAP1 is also termed as the partner of sld five 1 (PSF1). PSF1 belongs to the heterotetrameric complex, known as GINS. It is located on human chromosome 6p21.

Immunogen

Synthetic peptide directed towards the middle region of human TAP1

Application

Anti-TAP1 antibody has been used in immunoprecipitation.

Biochem/physiol Actions

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). TAP1 is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance. TAP1 is involved in the pumping of degraded cytosolic peptides across the endoplasmic reticulum into the membrane-bound compartment where class I molecules assemble. Mutations in this gene may be associated with ankylosing spondylitis, insulin-dependent diabetes mellitus, and celiac disease.
Knockdown of PSF1 expression blocks the multiplication of cell in lung cancer cells in vitro.

Sequence

Synthetic peptide located within the following region: LVTFVLYQMQFTQAVEVLLSIYPRVQKAVGSSEKIFEYLDRTPRCPPSGL
