Abstrakt: The effects of microinjections of exogenous casein kinase 2 on the structural organization of the maturing oocytes and eggs were studied in Xenopus laevis. Kinase inhibited the progesterone-stimulated oocyte maturation and induced dislocation of pigment granules. The morphological effect was shown to be dose-dependent. The results obtained are discussed in the light of the possible influence of casein kinase 2 on the organization of the cortical actin cytoskeleton through phosphorylation of actin-binding proteins.
