Applications
Inhibits IP3-mediated Ca2+ release
Functions
A potent and reversible inhibitor of IP3-mediated Ca2+ release, IC50 = 358 nM. Experiments with guinea-pig ileum permeabilized with alpha toxin revealed that Xestospongin C inhibits the IP3 receptor but not the ryanodine receptor in SR membranes. In intact smooth muscle cells it inhibits voltage-dependent Ca2+ and K+ currents at a concentration range similar to that at which it inhibits the IP3 receptor. It is a useful tool for probing the involvement of IP3 receptors in cellular signaling. Cell permeable.
Application Procedures
First dissolved in DMSO (up to 10 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 1 month.
