Facts about Serine/threonine-protein phosphatase PP1-beta catalytic subunit.
Part of the PTW/PP1 phosphatase complex, which plays a role in the control of chromatin structure and cell cycle progression during the transition from mitosis into interphase. According to CSNK1D and CSNK1E, determines the circadian period length, through the regulation of the rate and rhythmicity of PER1 and PER2 phosphorylation.
