FUN

 Protein phosphatase-1 (PP1) participates in the regulation of a wide variety of cellular functions by reversible protein phosphorylation. The ability of PP1 to regulate diverse functions resides in its capacity to interact with a variety of regulatory subunits that may target PP1 to specific subcellular locations, modulate its substrate specificity, and allow its activity to be responsive to extracellular signals. Several targeting subunits of PP1 have been identified, including the glycogen-binding subunits PPP1R3 (GEM:00.0/PPP1R3) and PPP1R4, and the nuclear inhibitor of PP1 (GEM:00.0/PPP1R8)."
