General description
A cell-permeable, reversible inhibitor of endoplasmic reticulum Ca2+-ATPase that releases Ca2+ from the same intracellular pools as thapsigargin. Mobilizes Ca2+ without increasing the levels of Ins(1,4,5)P3. Also known to inhibit sarcoplasmic reticular Ca2+-ATPase that is distinct from actomyosin ATPase. Bay K 8644 (Cat. No. 196878) can reverse the inhibitory effect of cyclopiazonic acid on the refilling of Ca2+ pools that have been depleted by repetitive stimulation with acetylcholine.
