Description générale

Protein phosphatase 2A (PP2A) is a specific protamine-kinase-inactivating phosphatase, one common physiological form of which is PP2A2.

Application

Protein phosphatase 2A2 has been used in a study to investigate two heat-stable protein inhibitors. It has also been used in a study to describe the purification and properties of a protamine kinase from bovine kidney microsomes.

Actions biochimiques/physiologiques

Protein Phosphatase 2A2 from bovine kidney was shown to be a unique inhibitor of protamine kinase while other phosphatases in the same family including PP1, PP2B, PP2C did not show any inhibition.

Définition de l'unité

One unit will release 1 nanomole of inorganic phosphate from (32)P-labeled phosphorylase per minute at pH 7.0 at 30 deg C.

Forme physique

Solution of 1 μg per vial in 50 μl of 50 mM Tris-HCl, pH 7.0, containing 14 mM β-Mercaptoethanol, 1mM benzamidine, 0.1 mM PMSF, 1mM EDTA, and 50% glycerol.

About an eightfold increase in protamine kinase activity was detected following extraction of highly purified microsomes from bovine kidney with 1% Triton X-100. Relative to the soluble fraction, the microsomes contained about 30% protamine kinase activity. The microsomal protamine kinase

Whole cell extracts from rat liver or spinach leaves contain divalent ion-independent protein histidine phosphatase activity due to phosphatases of the PP1/PP2A family. In the rat liver extract, almost all the activity was found in the PP1, PP2A1 and PP2A2

Two heat-stable protein inhibitors of protein phosphatase 2A (PP2A), tentatively designated I1PP2A and I2PP2A, have been purified to apparent homogeneity from extracts of bovine kidney. The purified preparations of I1PP2A exhibited an apparent M(r) approximately 30,000 and 250,000 as determined

Protein phosphatase (PP) 2A1, a trimer composed of A-, B- and C-subunits in the PP2A family, has been regarded as a principal form localizing at microtubules (MT), but PP2A2, the dimer of A- and C-subunits, has not. Substantiating the claim
