PPP1R12C Activators

Protein Phosphatase 1 Regulatory Subunit 12C (PPP1R12C), also known as Myosin Phosphatase Target Subunit 3 (MYPT3), is a protein that in humans is encoded by the PPP1R12C gene. This protein is part of the protein phosphatase 1 (PP1) regulatory subunits, which are essential for PP1 function.PP1 is a major serine/threonine phosphatase in eukaryotic cells, regulating a variety of cellular processes by dephosphorylating numerous substrates. The specificity of PP1 is determined by its regulatory subunits, which target PP1 to specific locations and substrates within the cell.

PPP1R12C is primarily expressed in the brain and heart. It has a conserved PP1 binding motif at its C-terminus, suggesting its role in targeting PP1 to specific substrates. Additionally, PPP1R12C contains a kinase-inducible domain interacting (KIX) domain, which is known to mediate protein-protein interactions in various signaling pathways.Although the precise biological functions of PPP1R12C are not fully understood, its association with PP1 suggests a role in a wide range of cellular processes, including protein synthesis, cell division, glycogen metabolism, muscle contraction, and neuronal signaling.
