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