[Calcium transport and role of 3',5'-AMP-dependent phosphorylation in its relation].

The role of calcium and mechanism regulating its concentration in a cell are considered. The author's own data and those available in literature are analyzed concerning the role of 3',5'-AMP-dependent phosphorylation of proteins of plasma membranes and endoplasmatic reticulum of different muscles in regulating 2+Ca transport. The problems of deciphering the mentioned regulatory system as well as the existing suppositions and hypothesis advanced for explaining the observed effect of cyclic nucleotides in regulation of 2+Ca transport are dealt with.
