Anti-cyclic nucleotide gated channel subunit alpha 2 antibodies are used for the immunodetection of the protein encoded by the CNGA2 gene. In humans, the canonical protein has a reported length of 664 amino acid residues and a mass of 76 kDa. Its subcellular localization is in the membrane. A member of the Cyclic nucleotide-gated cation channel (TC 1.A.1.5) protein family, it is known to be involved with the sensory perception of smell. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include CNCA1, CNG2, OCNC1, OCNCALPHA, OCNCa, cyclic nucleotide-gated olfactory channel, CNG channel alpha-2, and CNCA. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
