Anti-MSL1 antibodies are used in the immunodetection of the protein MSL complex subunit 1. In humans, the canonical protein has a reported length of 614 amino acid residues and a mass of 67.1 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. A member of the Msl-1 protein family, MSL1 is known to be a component of histone acetyltransferase complex responsible for the majority of histone H4 acetylation at 'Lys-16' (H4K16ac) which is implicated in the formation of higher-order chromatin structure. Post-translational modifications have been described, including sumoylation. Synonyms for this target antigen include MSL1-like 1, male specific lethal 1 homolog, male-specific lethal 1-like 1, male-specific lethal-1 homolog 1, and male-specific lethal 1 homolog. MSL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the MSL1 antibodies listed below. In addition, ELISA is also a common application.
