Anti-CD164 molecule antibodies are used in the immunodetection of the protein encoded by the CD164 gene. In humans, the canonical protein has a reported length of 197 amino acid residues and a mass of 20.9 kDa. Its subcellular localization is in the lysosomes, cell membrane, and is also secreted. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of the CD164 protein family, it is a reported sialomucin that may play a key role in hematopoiesis by facilitating the adhesion of CD34(+) cells to the stroma and by negatively regulating CD34(+)CD38(lo/-) cell proliferation. Post-translational modifications have been described, including O-glycosylation. Other names for this target antigen include MGC-24, MGC-24v, MUC-24, endolyn, sialomucin core protein 24, and DFNA66.
