Anti-SLC44A1 antibodies are used in the immunodetection of the protein solute carrier family 44 member 1. In humans, the canonical protein has a reported length of 657 amino acid residues and a mass of 73.3 kDa. Its subcellular localization is in the mitochondria and cell membrane. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in various cells of the hematopoietic system. A member of the CTL (choline transporter-like) protein family, it is known to be involved with transmembrane transport. Synonyms for this target antigen include CDW92, CHTL1, CONATOC, CTL1, choline transporter-like protein 1, and CD92.
