Protein phosphatase 2 (PP2), also known as PP2A, is an enzyme that in humans is encoded by the PPP2CA gene. The PP2A heterotrimeric protein phosphatase is ubiquitously expressed, accounting for a large fraction of phosphatase activity in eukaryotic cells. Its serine/threonine phosphatase activity has a broad substrate specificity and diverse cellular functions. Among the targets of PP2A are proteins of oncogenic signaling cascades, such as Raf, MEK, and AKT, where PP2A may act as a tumor suppressor.

  • プロテインホスファターゼ2 (protein phosphatase 2, PP2) は、普遍的に発現しているヘテロ三量体型プロテインホスファターゼで、PP2Aとしても知られる。真核生物細胞におけるホスファターゼ活性の大部分を担う。そのセリン/スレオニンホスファターゼ活性は広い基質特異性を持ち、多様な細胞機能に関与する。PP2Aの標的にはRaf、MEK、AKTといった発がん性シグナル伝達カスケードのタンパク質が含まれ、PP2Aはがん抑制因子として機能する。 (ja)
  • Белок фосфатазы 2 (PP2) (англ. Protein phosphatase 2), также известный как PP2A — фермент, кодируемый у человека геном PPP2CA. PP2A — гетеротримерная протеинфосфатаза, являющаяся убиквитарной и консервативной серин/треонин фосфатазой с широкой субстратной специфичностью и разнообразными клеточными функциями. Целями PP2A являются белки онкогенных сигнальных каскадов, такие как , , и AKT. (ru)
  • 蛋白磷酸酶2(英語:Protein phosphatase 2,簡稱PP2或PP2A)是由PPP2CA基因编码的蛋白磷酸酶。PP2A存在于很多组织中,為异三聚体,屬於丝氨酸/苏氨酸磷酸酶,具有广泛的底物特异性和多样的细胞功能。PP2A的底物都是信号传导级联反应中的癌蛋白,如AKT、和。 (zh)
  • La protéine phosphatase 2 (PP2), également appelée PP2A, est une enzyme qui, chez l'homme, est codée par les gènes PPP2CA (isoforme α) et PPP2CB (isoforme β) situés sur le chromosome 5 et le chromosome 8 respectivement. Il s'agit d'une protéine hétérotrimérique exprimée de manière ubiquitaire qui assure une partie importante de l'activité phosphatase dans les cellules d'eucaryotes. Son activité phosphatase est caractérisée par une large spécificité de substrats et une grande diversité de fonctions cellulaires. Parmi les cibles de la protéine phosphatase 2, on compte notamment les protéines des cascades de signalisation oncogène comme c-Raf, (en) et Akt1, vis-à-vis desquelles elle agit comme suppresseur de tumeur.
