Abstract

IP3 activates intracellular calcium release by binding to an intracellular ligand gated calcium permeable channel which has been shown to be regulated by protein kinase A phosphorylation. Two consensus sequences for protein kinase A phosphorylation are predicted by the recently isolated cDNA of the mouse and rat. In the present study we have isolated and sequenced the two peptides in the rat IP3 receptor which are phosphorylated by protein kinase A and demonstrate protein kinase A phosphorylation on S-1755 and S-1589.
