Activation of the calcium release channel (ryanodine receptor) by heparin and other polyanions is calcium dependent.

Heparin has been used as a potent competitive inhibitor of inositol 1,4,5-trisphosphate (IP3)-binding to IP3 receptors and to block IP3-gated calcium channels in bilayer experiments. In contrast to the effect on the IP3-gated channel, heparin (0.1-1 micrograms/ml) opened the Ca release channel (ryan...
