Anti-MRTFB antibodies are used in the immunodetection of the protein myocardin related transcription factor B. In humans, the canonical protein has a reported length of 1088 amino acid residues and a mass of 118.1 kDa. Its subcellular localization is in the nucleus. Up to 5 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. MRTFB is known to act as a transcriptional coactivator of serum response factor (SRF). Post-translational modifications have been described, including O-glycosylation. Synonyms for this target antigen include MKL and myocardin family member 2, MKL/myocardin like 2, MKL/myocardin-like protein 2, MKL1/myocardin like 2, megakaryoblastic leukemia 2, and CTA-276F8.1. MRTFB gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MRTFB 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.
