Notch resolves mixed neural identities in the

Upon binding by ligands from the DSL family (for Delta, Serrate, Lag2), Notch is proteolyzed and its intracellular domain (Notchintra) translocates to the nucleus, where, together with co-factors, it activates transcription (Bray, 2006). Notch is required at several stages during neural development ...

Channelrhodopsin
Channelrhodopsins are a subfamily of retinylidene proteins (rhodopsins) that function as light-gated ion channels. They serve as sensory photoreceptors in unicellular green algae, controlling phototaxis: movement in response to light. Expressed in cells of other organisms, they enable light to control electrical excitability, intracellular acidity, calcium influx, and other cellular processes. Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) from the model organism Chlamydomonas reinhardtii are the first discovered channelrhodopsins. Variants have been cloned from other algal species, and more are expected.
