TL;DR: It is proposed that STIM1, a ubiquitously expressed protein that is conserved from Drosophila to mammalian cells, plays an essential role in SOC influx and may be a common component of SOC and CRAC channels.

TL;DR: It is proposed that STIM1 functions as the missing link between Ca2+ store depletion and SOC influx, serving as aCa2+ sensor that translocates upon store depletion to the plasma membrane to activate CRAC channels.

TL;DR: Using an unbiased genome-wide RNA interference screen in Drosophila S2 cells, 75 hits are identified that strongly inhibited Ca(2+) influx upon store emptying by thapsigargin, including Stim and olf186-F, a member of a highly conserved family of four-transmembrane spanning proteins with homologs from Caenorhabditis elegans to human.

TL;DR: Using a rat neuropathic pain model in which gabapentin-sensitive tactile allodynia develops after tight ligation of the left fifth and sixth lumbar spinal nerves, a >17-fold, time-dependent increase in α2δ subunit expression in DRGs ipsilateral to the nerve injury is found, suggesting that DRG α2 δ regulation may play an unique role in neuroplasticity after peripheral nerve injury.

TL;DR: The data show that the FHM mutations can lead to both gain- and loss-of-function of human P/Q-type calcium channels.
