Beschreibung

General description

Protein Phosphatase 2A1 (PP2A1) belongs to the PP2A family and comprises trimeric A, B and C subunits.[1] PPA2 enzymes are serine/threonine phosphatases[2] and exist as several isoforms.[3]

Application

Protein phosphatase 2A₁ has been used to treat human fibroblast cells prior to western blot analysis[4].

Biochem/physiol Actions

Protein Phosphatase 2A is a cytoplasmic protein, which colocalizes with microtubule proteins and is involved in the dephosphorylation of the tau protein and oncoprotein 18. Protein Phosphatase 2A1 (PP2A1) binds to polymerized microtubule proteins and may be targeted by tubulin in modulating phosphatase activity.[1] PP2A1 is implicated as a growth suppressor and is associated with dysregulation in cancer.[2] It also regulates cell cycle, RNA splicing differentiation, and signal transduction.[2] PP2A dysfunction is correlated to the tau protein deregulation in Alzheimer′s disease pathophysiology.[3] Protein Phosphatase 2A1 is a divalent cation-dependent protein serine/threonine phosphatase implicated as a growth suppressor and is associated with dysregulation in cancer.

Physical form

Solution in 50 mM Tris-HCl, pH 7.0, containing 14 mM 2-mercaptoethanol, 1 mM benzamidine, 0.1 mM PMSF, 1 mM EDTA, and 50% glycerol

Other Notes

One unit will release 1.0 nanomole of phosphate from ³²P-labeled phosphorylase A per minute at pH 7.0 at 30 °C.
