Anti-MCTS1 antibodies are used in the immunodetection of the protein MCTS1 re-initiation and release factor. In humans, the canonical protein has a reported length of 181 amino acid residues and a mass of 20.6 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the MCTS1 protein family, MCTS1 is a reported anti-oncogene that plays a role in cell cycle regulation; decreases cell doubling time and anchorage-dependent growth; shortens the duration of G1 transit time and G1/S transition. Synonyms for this target antigen include MCT1, malignant T-cell-amplified sequence 1, malignant T-cell amplified sequence 1, multiple copies T-cell malignancies, multiple copies in T-cell lymphoma-1, and MCT-1. MCTS1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MCTS1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
