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 ]
I 1 PP2A has a highly acidic C-terminal tail and the N-terminus is leucine/isoleucine rich (Li et al., 1996). In the presence of physiological conditions of Mn 2+, I 1 PP2A can also associate with and stimulate the activity of PP1 but Mn 2+ also does not affect the inhibition of PP2A through I 1 PP2A, in vitro (Janssens & Goris, 2001).
Protein phosphatase 2A (PP2A) is a major intracellular protein phosphatase that regulates multiple aspects of cell growth and metabolism. Phosphorylation enables the activation or The ability of this widely distributed heterotrimeric enzyme to act on a diverse array of substrates is largely controlled by the nature of its regulatory B subunit ...
The largest class of PPs is the phosphoprotein phosphatase (PPP) family comprising PP1, PP2A, PP2B, PP4, PP5, PP6 and PP7, and the protein phosphatase Mg 2+ - or Mn 2+-dependent (PPM) family, composed primarily of PP2C.
PP2A is involved in multiple regulatory processes, such as DNA replication, metabolism, transcription, and development. PP2B, also called calcineurin , is involved in the proliferation of T cells ; because of this, it is the target of some drugs that seek to suppress the immune system.
