WebOct 30, 2009 · Structure and Mechanism of Protein Phosphatase 1 (A) Structure of the catalytic subunit (blue) of protein phosphatase 1 (PP1) bound to okadaic acid (OA, yellow ball and stick). A Y-shaped surface groove (pink) is defined by the three domains of PP1. The two metal ions (red spheres) are Mn 2+ (manganese) and Fe 2+ (iron). WebPP1 is a serine / threonine specific protein phosphatase known to be involved in the regulation of a variety of cellular processes, such as cell division, glycogen metabolism, muscle contractility, protein synthesis, and HIV-1 viral transcription. Mouse studies suggest that PP1 functions as a suppressor of learning and memory.
