[Effect of fluoroaluminate on the passive transport of calcium in the plasma membrane fraction of the pig myometrium].
Study of the effect of aluminium, fluoride-ions and fluoroaluminium on the passive transport of Ca2+ through the plasma membrane of the myometrium cells has shown that 10 microM of Al3+, 1 mM of F- and the both ions taken in the mentioned concentrations do not affect this process. At the same time 10 mM of F- as well as 10 microM of Al3+ together with 10 mM of F- inhibit a passive output of calcium from vesicles. The results obtained suppose that inhibitory regulation of the passive transport of calcium in the myometrium sarcolemma is executed through Gi-protein.
