Protein phosphatase 2 (PP2), also known as PP2A, is an enzyme that in humans is encoded by the PPP2CA gene. [ 2 ] [ 3 ] The PP2A heterotrimeric protein phosphatase is ubiquitously expressed, accounting for a large fraction of phosphatase activity in eukaryotic cells. [ 4 ]
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 ...

An added substance that lowers the rate is called a reaction inhibitor if reversible and catalyst poisons if irreversible. [1] Promoters are substances that increase the catalytic activity, even though they are not catalysts by themselves. [46] Inhibitors are sometimes referred to as "negative catalysts" since they decrease the reaction rate. [47]
A catalytic triad is a set of three coordinated amino acid residues that can be found in the active site of some enzymes. [1] [2] Catalytic triads are most commonly found in hydrolase and transferase enzymes (e.g. proteases, amidases, esterases, acylases, lipases and β-lactamases).
The most highly expressed regulatory subunit is p85α; all three catalytic subunits are expressed by separate genes (Pik3ca, Pik3cb, and Pik3cd for p110α, p110β, and p110δ, respectively). The first two p110 isoforms (α and β) are expressed in all cells, but p110δ is expressed primarily in leukocytes , and it has been suggested that it ...
Calcineurin is a heterodimer of a 61-kD calmodulin-binding catalytic subunit, calcineurin A and a 19-kD Ca 2+-binding regulatory subunit, calcineurin B.There are three isozymes of the catalytic subunit, each encoded by a separate gene (PPP3CA, PPP3CB, and PPP3CC) and two isoforms of the regulatory, also encoded by separate genes (PPP3R1, PPP3R2).
