title: Extending optogenetics to a Ca(2+)-selective channel.
abstract: Many cellular processes are regulated by Ca(2+) signaling. In this issue of Chemistry & Biology, Pham et al. have developed a photo-activated protein, LOVS1K, which enables the generation of local or global Ca(2+) signals through binding to the Ca(2+)-specific membrane channel Orai.
