A Novel Modulator of STIM2-Dependent Store-Operated Ca2+ Channel Activity

Store-operated Ca(2+) entry is one of the main pathways of calcium influx into non-excitable cells, which entails the initiation of many intracellular processes. The endoplasmic reticulum Ca(2+) sensors STIM1 and STIM2 are the key components of store-operated Ca(2+) entry in mammalian cells. Under p...

description Store-operated Ca(2+) entry is one of the main pathways of calcium influx into non-excitable cells, which entails the initiation of many intracellular processes. The endoplasmic reticulum Ca(2+) sensors STIM1 and STIM2 are the key components of store-operated Ca(2+) entry in mammalian cells. Under physiological conditions, STIM proteins are responsible for store-operated Ca(2+) entry activation. The STIM1 and STIM2 proteins differ in their potency for activating different store-operated channels. At the moment, there are no selective modulators of the STIM protein activity. We screened a library of small molecules and found the 4-MPTC compound, which selectively inhibited STIM2-dependent store-operated Ca(2+) entry (IC50 = 1 μM) and had almost no effect on the STIM1-dependent activation of store-operated channels.
