Serine/threonine-protein phosphatase PP1-beta catalytic subunit is an enzyme that in humans is encoded by the PPP1CB gene.[5]

The protein encoded by this gene is one of the three catalytic subunits of protein phosphatase 1 (PP1). PP1 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. Two alternatively spliced transcript variants encoding distinct isoforms have been observed.[6]

Interactions

edit

PPP1CB has been shown to interact with PPP1R15A,[7][8] Nucleolin,[9] SMARCB1[7] and PPP1R9B.[10]
