Anti-protocadherin alpha subfamily C, 2 antibodies are used in the immunodetection of the protein encoded by the PCDHAC2 gene. In humans, the canonical protein has a reported length of 1007 amino acid residues and a mass of 109.5 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. The protocadherin alpha subfamily C, 2 protein is involved with cell adhesion and nervous system development, among other functions. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include protocadherin alpha-C2.
