title: G proteins and calcium channels in myocardium.
abstract: Calcium mobilization has been demonstrated to possess functional importance in myocardial excitation-contraction as well as cellular metabolism. So far, much progress has been made to explore the possibility of involvement of guanine nucleotide binding regulatory protein in the opening and closing of calcium channels as well as intracellular second messenger (cyclic adenosine monophosphate and inositol triphosphate) -mediated calcium mobilization, although such work is still in its preliminary stage, the results have proved highly interesting and significant.
