Anti-ctr5 antibodies enable researchers to detect and measure the ctr5 antigen in biological samples. This target is a reported synonym of the SLC6A8 gene, which encodes solute carrier family 6 member 8. This protein is known to function in muscle contraction, among other biological roles. The human version of ctr5 has a canonical amino acid length of 635 residues and a protein mass of 70.5 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane of cells. ctr5 is a member of the Sodium:neurotransmitter symporter (SNF) (TC 2.A.22) protein family.
