Summaries for PPP2CB Gene

Entrez Gene Summary for PPP2CB Gene

  • This gene encodes the phosphatase 2A catalytic subunit. 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. This gene encodes a beta isoform of the catalytic subunit. [provided by RefSeq, Mar 2010]

GeneCards Summary for PPP2CB Gene

PPP2CB (Protein Phosphatase 2, Catalytic Subunit, Beta Isozyme) is a Protein Coding gene. Among its related pathways are PI3K-Akt signaling pathway and Signaling by FGFR. GO annotations related to this gene include protein C-terminus binding and protein serine/threonine phosphatase activity. An important paralog of this gene is PPP4C.

UniProtKB/Swiss-Prot for PPP2CB Gene

  • PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase.

Tocris Summary for PPP2CB Gene

  • Protein ser/thr phosphatases are a group of enzymes that catalyze the removal of phosphate groups from serine and/or threonine residues by the hydrolysis of phosphoric acid monoesters. They directly oppose the actions of kinases and phosphorylases and therefore play an integral role in many signal transduction pathways. There are two groups of serine/threonine phosphatases; phosphoprotein phosphatases (e.g. PP1, calcineurin), which are sensitive to okadaic acid and metallo-phosphatases (e.g. PP2C), which require a divalent cation, commonly Mg2+, for catalytic activity. Dephosphorylation, depending on the residue that the phosphate group is removed from, can have a stimulatory or inhibitory effect on the target molecule. This makes protein Ser/Thr phosphatases essential for many signal transduction pathways. Protein Ser/Thr phosphatase are regulated by their subcellular localization and by inhibitor proteins, which are subtype-specific.

    Quaternary structure:
    • Found in a complex with at least ARL2, PPP2CB, PPP2R1A, PPP2R2A, PPP2R5E and TBCD. Interacts with TBCD (By similarity). PP2A consists of a common heterodimeric core enzyme (composed of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant regulatory subunit (PR65) (subunit A)) that associates with a variety of regulatory subunits. Proteins that associate with the core dimer include three families of regulatory subunits B (the R2/B/PR55/B55, R3/B/PR72/PR130/PR59 and R5/B/B56 families), the 48 kDa variable regulatory subunit, viral proteins, and cell signaling molecules. Binds PPME1. May indirectly interact with SGOL1, most probably through regulatory B56 subunits. Interacts with CTTNBP2NL.

Post-translational modifications for PPP2CB Gene

  • Phosphorylation of either threonine (by autophosphorylation-activated protein kinase) or tyrosine results in inactivation of the phosphatase. Auto-dephosphorylation has been suggested as a mechanism for reactivation
  • Reversibly methyl esterified on Leu-309 by leucine carboxyl methyltransferase 1 (LCMT1) and protein phosphatase methylesterase 1 (PPME1). Carboxyl methylation influences the affinity of the catalytic subunit for the different regulatory subunits, thereby modulating the PP2A holoenzymes substrate specificity, enzyme activity and cellular localization.
  • Ubiquitination at Lys21, Lys41, Lys136, and Lys283
  • Modification sites at PhosphoSitePlus
