Anti-striatin 3 antibodies are used for the immunodetection of the protein encoded by the STRN3 gene. In humans, the canonical protein has a reported length of 797 amino acid residues and a mass of 87.2 kDa. Its subcellular localization is in the membrane and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the WD repeat striatin protein family, it is known to bind calmodulin in a calcium dependent manner. Other names for this target antigen include S/G2NA, SG2NA, cell cycle S/G2 nuclear autoantigen, cell cycle autoantigen SG2NA, nuclear autoantigen, and PPP2R6B. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of striatin 3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
