This volume is a collection of papers contributed by partici pants in the Symposium on Recent Advances in Ca]+ and Cell Function, Calmodulin and Intracellular Ca++ Receptors, held in Kyoto, Japan, July 25-29, 1981. This meeting was one of the satellite symposia to the 8th International Congress of Pharmacology (Tokyo, 1981). Calcium ion is a well known intracellular messenger. Since troponin and calmodulin were found to be intracellular medi ators of a number of actions of Ca++, the functions of this ion, with relevance to its intracellular receptive proteins, have received a great deal of...
