The inhibitory effects of thapsigargin, cyclopiazonic acid, and 2,5-di(tert-butyl)hydroquinone, and 1,3-dibromo-2,4,6-tri(methylisothiouronium)benzene on the Ca(2+) ATPase were characterized by comparative measurements of sequential reactions of the catalytic...

Store-operated Ca2+ entry (SOCE), a major mechanism for Ca2+ entry in non-excitable cells, is regulated by the filling state of the intracellular Ca2+ stores. We have previously reported that a de novo conformational coupling between the type II IP3 receptor ...

The indole alkaloid cyclopiazonic acid (CPA) is one of the few known nanomolar inhibitors of sarco(endo)plasmic reticulum Ca²⁺-ATPase (SERCA) besides the anticancer drug thapsigargin and the antiplasmoidal terpenoid artemisinin. Due to its less complex struct...

Properties of the sarcoplasmic reticulum (SR) with respect to Ca(2+) loading and release were measured in mechanically skinned fiber preparations from isolated extensor digitorum longus (EDL) muscles of the rat that were either kept at room temperature (23 de...

Considering the physiological Ca2+ dynamics within the ER (endoplasmic reticulum), it remains unclear how efficient protein folding is maintained in living cells. Thus, utilizing the strictly folding-dependent activity and secretion of LPL (lipoprotein lipase...
