Anti-hCTR1 antibodies enable researchers to detect and measure the hCTR1 antigen in biological samples. This target is a reported synonym of the SLC31A1 gene, which encodes solute carrier family 31 member 1. This protein is known to function in angiogenesis and the transport of ions, among other biological roles. The human version of hCTR1 has a canonical amino acid length of 190 residues and a protein mass of 21.1 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the adrenal gland, tonsil, and adipose tissue. hCTR1 is a member of the Copper transporter (Ctr) (TC 1.A.56) protein family.
