Anti-CALY antibodies are used in the immunodetection of the protein calcyon neuron specific vesicular protein. In humans, the canonical protein has a reported length of 217 amino acid residues and a mass of 23.4 kDa. Its subcellular localization is in the cytoplasmic vesicles and cell membrane. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in the pyramidal cells of the prefrontal cortex, in hippothalamus and in caudate nucleus. It is a member of the NSG protein family. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include NSG3, neuron-specific vesicular protein calcyon, D1 dopamine receptor-interacting protein, calcyon D1 dopamine receptor-interacting protein (CALCYON), and DRD1IP. CALY gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. These CALY antibodies are widely used in Western Blot experiments, among other applications.
