Anti-B9D2 antibodies are used in the immunodetection of the protein B9 domain containing 2. In humans, the canonical protein has a reported length of 175 amino acid residues and a mass of 19.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the B9D protein family, B9D2 is a known component of the tectonic-like complex, a complex localized at the transition zone of primary cilia and acting as a barrier that prevents diffusion of transmembrane proteins between the cilia and plasma membranes. The B9D2 gene has been associated with the disease, Meckel syndrome. Synonyms for this target antigen include B9 protein domain 2, MKS1-related protein 2, involved in cIlia stability-1, and B9 domain-containing protein 2. B9D2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the B9D2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
