Anti-LRRC39 antibodies are used in the immunodetection of the protein leucine rich repeat containing 39. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 38.8 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in skeletal muscle and heart. LRRC39 is a known component of the sarcomeric M-band which plays a role in myocyte response to biomechanical stress. Synonyms for this target antigen include densin hlg, myomasp, myosin-interacting M-band-associated stress-responsive protein, and leucine-rich repeat-containing protein 39. LRRC39 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These LRRC39 antibodies are widely used in Western Blot experiments, among other applications.
