PPP1R12A (Myosin phosphatase-targeting subunit 1)

PPP1R12A(Protein phosphatase 1 regulatory subunit 12A), also called MYPT1(Myosin phosphatase target subunit 1), is an enzyme that in humans is encoded by the PPP1R12A gene. PPP1R12A is one of the subunits of myosin phosphatase. Sequencing analysis showed that human PPP1R12A contains 1,030 amino acids with a calculated molecular mass of approximately 115 kD. The PPP1R12A gene is mapped on 12q21.2-q21.3. PPP1R12A is the protein that regulates PP1 function in smooth muscle relaxation. The cellular MYPT1-PP1-delta -specific inhibitor CPI17 caused a loss of merlin function characterized by merlin phosphorylation, Ras activation, and transformation. Jin et al. concluded that PPP1R12A and its substrate merlin are part of a previously undescribed tumor suppressor cascade that can be hindered in 2 ways, by mutation of the NF2 gene and by upregulation of the oncoprotein CPI17.\n\nUniProt Number:\nO14974\n\nGene ID:\nPPP1R12A\n\nApplications:\nSuitable for use in Western Blot.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Handling:\nStore at -20?C for one year.
