Anti-MAST2 antibodies are used in the immunodetection of the protein microtubule associated serine/threonine kinase 2. In humans, the canonical protein has a reported length of 1798 amino acid residues and a mass of 196.4 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis. A member of the AGC Ser/Thr protein kinase protein family, MAST2 is known to be involved with cytoskeleton organization and intracellular signal transduction. Post-translational modifications have been described, including ubiquitination, protein cleavage and phosphorylation. Synonyms for this target antigen include MTSSK, microtubule-associated serine/threonine-protein kinase 2, microtubule associated testis specific serine/threonine protein kinase, and MAST205. MAST2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MAST2 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
