Editorial: Molecular Components of Store-Operated Calcium Entry in Health and Disease

Description

Store-Operated Calcium Entry (SOCE) is a ubiquitous Ca2+ influx mechanism first described in 1986 (Putney, 1986). This conserved mechanism results from the interaction between the tetraspanning ORAI1 channel located in plasma membrane and the unique endoplasmic reticulum (ER) Ca2+ sensor, stromal interaction molecule 1 (STIM1), via their respective intracellular domains (Roos et al., 2005; Csutora et al., 2008). Moreover, there are two homologs of ORAI1, namely ORAI2 and ORAI3, all generating SOCE with the same mechanism.
