Anti-syntrophin beta 1 antibodies are used for the immunodetection of the protein encoded by the SNTB1 gene. In humans, the canonical protein has a reported length of 538 amino acid residues and a mass of 58.1 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is ubiquitously expressed across many tissue types. A member of the Syntrophin protein family, it is a reported adaptor protein that binds to and probably organizes the subcellular localization of a variety of membrane proteins. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include 59-DAP and A1B. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Some syntrophin beta 1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
