[Isolation and properties of the Ca2+, phospholipid-dependent protein kinase from the substantia grisea of the rat brain in the early stage of exposure to ionizing radiation].

Ca2+, phospholipid-dependent proteinkinase was isolated from intact and exposed (1 h following whole body X-irradiation with a dose of 0.21 C/kg) gray substance of rat brain, and the dependence of this enzyme on pH and temperature, and substrate specificity were studied. Changes were shown to occur in some Ca2+, phospholipid-dependent proteinkinase properties under the effect of X-radiation while the substrate specificity remained unchanged.
