[Effect of 1-methyladenine on localization of Galpha1-protein in starfish oocytes].
Localization and quantitative dynamics of alpha i subunit of G protein was studied by electron immunocytochemistry and immunoenzyme assay after hormonal induction of maturation in Asterias amurensis starfish oocytes. G alpha i protein was chiefly localized in the plasma membrane of immature oocytes; 1-methyladenine induced redistribution of the alpha i protein from the plasma membrane to intracellular structure up to the germinal physical breakdown.
