Mobilizes Ca²⁺ specifically from Ins(1,4,5)P₃-sensitive Ca²⁺ stores by inhibiting microsomal and sarcoplasmic reticulum Ca²⁺-ATPase activity. Does not affect mitochondrial Ca²⁺ fluxes or plasma membrane Ca²⁺/Mg²⁺ ATPase activity. Inhibits prostaglandin E₂ and prostacyclin formation in osteoblast-like cell lines.

Mobilizes Ca²⁺ specifically from the Ins(1,4,5)P₃-sensitive Ca²⁺ stores by inhibiting microsomal and sarcoplasmic reticulum Ca²⁺-ATPase activity. Does not affect mitochondrial Ca²⁺ fluxes or plasma membrane Ca²⁺/Mg²⁺ ATPase activity. Useful for the study of endomembrane Ca²⁺ stores and plasma membrane Ca²⁺ permeability pathways.

Cell permeable: no

Primary Target
micosomal and sarcoplasmic reticulation Ca²⁺ ATPase activity

Product does not compete with ATP.

Reversible: no

Toxicity: Standard Handling (A)
