Human Gene PPP2CB (ENST00000221138.9) from GENCODE V41
  Description: Homo sapiens protein phosphatase 2 catalytic subunit beta (PPP2CB), mRNA. (from RefSeq NM_001009552)
RefSeq Summary (NM_001009552): 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].

  ID: PP2AB_HUMAN
DESCRIPTION: RecName: Full=Serine/threonine-protein phosphatase 2A catalytic subunit beta isoform; Short=PP2A-beta; EC=3.1.3.16;
FUNCTION: PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase.
CATALYTIC ACTIVITY: A phosphoprotein + H(2)O = a protein + phosphate.
COFACTOR: Binds 1 iron ion per subunit (By similarity).
COFACTOR: Binds 1 manganese ion per subunit (By similarity).
SUBUNIT: 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.
INTERACTION: P78318:IGBP1; NbExp=3; IntAct=EBI-1044367, EBI-1055954;
SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Chromosome, centromere. Cytoplasm, cytoskeleton, spindle pole. Note=In prometaphase cells, but not in anaphase cells, localizes at centromeres. During mitosis, also found at spindle poles.
PTM: Reversibly methyl esterified on Leu-309. Carboxyl methylation may play a role in holoenzyme assembly. It varies during the cell cycle. Demethylated by PME1 (in vitro).
PTM: 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.
SIMILARITY: Belongs to the PPP phosphatase family. PP-1 subfamily.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
