Myosin Phosphatase 2: Lysates

PPP1R12B, also known as Protein phosphatase 1 regulatory subunit 12B, has 5 isoforms, a 982 amino acid isoform that is 110 kDa, a 386 amino acid isoform that is 43 kDa, a 224 amino acid isoform that is 26 kDa, a 208 amino acid isoform that is 24 kDa, and a 515 amino acid isoform that is 58 kDa; detected in skeletal muscle, fetal and adult heart, brain, placenta, kidney, spleen, thymus, pancreas and lung; with cytoplasmatic subcellular location; regulates myosin phosphatase activity and augments Ca(2+) sensitivity of the contractile apparatus. This protein is being studied for its involvement in breast cancer. The PPP1R12B protein has been shown to involve IL16, PPP1CB, PRKG1, HSPA8, MYL6, and MYL6B in RhoA pathway, PKA signaling, actin-based motility by Rho family GTPases, eIF2 pathway, CDK5 pathway, insulin pathway, G2/M transition, cell cycle, mitotic G2-G2/M phases, regulation of PLK1 activity at G2/M transition, cell cycle, mitotic, and vascular smooth muscle contraction pathways.
