Anti-MYL1 antibodies are used in the immunodetection of the protein myosin light chain 1. In humans, the canonical protein has a reported length of 194 amino acid residues and a mass of 21.1 kDa. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the skeletal muscle. MYL1 is known to be involved with muscle contraction. Post-translational modifications have been described, including acetylation. The MYL1 gene has been associated with the disease, Myopathy. Synonyms for this target antigen include MLC-1, MLC1, MLC1/3, MLC1F, MLC3F, MYOFTA, myosin light chain 1/3, skeletal muscle isoform, and CMYP14. MYL1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 60 citations in the literature describe the use of MYL1 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
