{{Infobox_gene}}Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit beta isoform is an enzyme that in humans is encoded by the PPP2R5B gene.[1][2] Function The product of this gene belongs to the phosphatase 2A regulatory subunit B family. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes a beta isoform of the regulatory subunit B56 subfamily.[2] Interactions PPP2R5B has been shown to interact with PPP2R1B[3] and PPP2CA.[3][4] References 1. ^{{cite journal | vauthors = McCright B, Virshup DM | title = Identification of a new family of protein phosphatase 2A regulatory subunits | journal = The Journal of Biological Chemistry | volume = 270 | issue = 44 | pages = 26123–8 | date = Nov 1995 | pmid = 7592815 | pmc = | doi = 10.1074/jbc.270.44.26123 }} 2. ^1 {{cite web | title = Entrez Gene: PPP2R5B protein phosphatase 2, regulatory subunit B', beta isoform| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=5526| accessdate = }} 3. ^1 {{cite journal | vauthors = McCright B, Rivers AM, Audlin S, Virshup DM | title = The B56 family of protein phosphatase 2A (PP2A) regulatory subunits encodes differentiation-induced phosphoproteins that target PP2A to both nucleus and cytoplasm | journal = The Journal of Biological Chemistry | volume = 271 | issue = 36 | pages = 22081–9 | date = Sep 1996 | pmid = 8703017 | doi = 10.1074/jbc.271.36.22081 }} 4. ^{{cite journal | vauthors = Goudreault M, D'Ambrosio LM, Kean MJ, Mullin MJ, Larsen BG, Sanchez A, Chaudhry S, Chen GI, Sicheri F, Nesvizhskii AI, Aebersold R, Raught B, Gingras AC | title = A PP2A phosphatase high density interaction network identifies a novel striatin-interacting phosphatase and kinase complex linked to the cerebral cavernous malformation 3 (CCM3) protein | journal = Molecular & Cellular Proteomics | volume = 8 | issue = 1 | pages = 157–71 | date = Jan 2009 | pmid = 18782753 | pmc = 2621004 | doi = 10.1074/mcp.M800266-MCP200 }}
