Anti-TAP1 Antibody, clone mAb 148.3

32160702

NA.41

Peptide transporter TAP1 is also called Antigen peptide transporter 1 (APT1), ATP-binding cassette sub-family B member 2 (ABCB2), Peptide supply factor 1 (PSF1), Peptide transporter PSF1 (PSF-1), Peptide transporter involved in antigen processing 1, and Really interesting new gene 4 protein (RING4). TAP1 is involved in the transport of antigens from the cytoplasm to the endoplasmic reticulum for association with MHC class I molecules as well as MHC class I folding. TAP1 is inhibited herpes simplex virus ICP47 protein, human cytomegalovirus US6 glycoprotein, human adenovirus E3-19K glycoprotein, and is down-regulated by human Epstein-Barr virus vIL-10 protein. TAP1 mutations can be a cause of Bare lymphocyte syndrome 1 (BLS1).

Epitope: This antibody recognizes the ADAPE amino acid residues within the CYWAMVQAPADAPE sequence of human TAP1 (located at the C-terminus).
Linear peptide corresponding to the CYWAMVQAPADAPE sequence of human TAP1.
