25769459 Orai1, Orai2 and STIM1 form functional Ca(2+) release-activated Ca(2+) channels in OUMS-27 cells (chondrocytes) and that these complexes are responsible for sustained Ca(2+) entry in response to agonist stimulation.
24603752 The higher amplitude of store-operated Ca2+ entry was associated to the over-expression for Stim2, Orai2-3, and TRPC1 while Stim2 levels remained constant and Stim1, Orai1, Orai3, TRPC1 and TRPC4 proteins were over-expressed in primary myelofibrosis.
24040356 Orai1 but not Orai2 plays a major role in the influx of extracellular Ca2+ into and mediator release from HLMCs following their activation
22640869 Orai1 and Orai2 operate in a STIM-dependent manner, Orai3 does not interact with STIM isoforms upon calcium store depletion in platelets.
20607548 With these data we show a new Ca(2)(+) entry pathway linked to the Ca(2)(+)/inositolphosphate second-messenger system in RPE cells which help to further understand regulatory pathways of agonists.
19706554 Data show that the fast Ca(2+)-dependent inactivation is mediated by three conserved glutamates in the C termini (CT) of Orai2 and Orai3, which show prominent fast Ca(2+)-dependent inactivation compared with Orai1.
19506081 analysis of activation of Orai1-3 channels by a STIM1 coiled-coil mutant
18403424 The effects of 2-aminoethoxydiphenyl borate on orai1, orai2, orai3 metabolism in HEK293 cells with and without STIM1 are reported.
17452328 Results suggest that Orai1, -2, and -3 channels are similarly inhibited by extracellular calcium, indicating similar affinities for Ca(2+) within the selectivity filter.
