Anti-B0at1 antibodies enable researchers to detect and measure the B0at1 antigen in biological samples. This target is a reported synonym of the SLC6A19 gene, which encodes solute carrier family 6 member 19. This protein is a reported transporter that mediates resorption of neutral amino acids across the apical membrane of renal and intestinal epithelial cells. The human version of B0at1 has a canonical amino acid length of 634 residues and a protein mass of 71.1 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the small intestine, rectum, kidney, gallbladder, and duodenum. B0at1 is a member of the Sodium:neurotransmitter symporter (SNF) (TC 2.A.22) protein family.
