Anti-STAC3 antibodies are used in the immunodetection of the protein SH3 and cysteine rich domain 3. In humans, the canonical protein has a reported length of 364 amino acid residues and a mass of 41.5 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 3 different isoforms have been reported for this protein. STAC3 is reported to be required for normal excitation-contraction coupling in skeletal muscle and for normal muscle contraction in response to membrane depolarization. The STAC3 gene has been associated with the disease, Myopathy. Synonyms for this target antigen include SH3 and cysteine-rich domain-containing protein 3. STAC3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of STAC3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
