Anti-CNTNAP5 antibodies are used in the immunodetection of the protein contactin associated protein family member 5. In humans, the canonical protein has a reported length of 1306 amino acid residues and a mass of 145.6 kDa. Its subcellular localization is in the membrane. A member of the Neurexin protein family, CNTNAP5 is believed to play a role in the correct development and proper functioning of the peripheral and central nervous system and be involved in cell adhesion and intercellular communication. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include cell recognition molecule Caspr5, contactin associated protein like 5, and contactin-associated protein-like 5. CNTNAP5 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. These CNTNAP5 antibodies are widely used in Western Blot experiments, among other applications.
