    ATP regulates cardiac Ca2+ channel activity via a mechanism independent of protein phosphorylation

     The role of adenosine triphosphate (ATP) in the regulation of L-type Ca2+ channel activity was investigated in inside-out patches from guinea-pig ventricular cells, in which the Ca2+ channel activity had been re...
