A widely used inhibitor of the ubiquitous sarco-endoplasmic reticulum Ca(2+)-ATPases in mammalian cells. It acts as a potent, cell-permeable, IP3-independent intracellular calcium releaser that blocks the transient increase in intracellular Ca2+ induced by angiostatin and endostatin. It induces apoptosis by disrupting intracellular free Ca2+ levels.
