Cry2

Cryptochrome 2 (CRY2) is a blue light stimulated photoreceptor, when exposed to blue light, it would interact with CIB1. Technically, we use 488nm laser of confocal microscope, which also activate GFP, to stimulate the binding of two light-control element. Functionally, it is used to fuse with other protein and bring them together into phase under light.

Usage and Biology

Photoreceptor that mediates primarily blue light inhibition of hypocotyl elongation and photoperiodic control of floral initiation, and regulates other light responses, including circadian rhythms, tropic growth, stomata opening, guard cell development, root development, bacterial and viral pathogen responses, abiotic stress responses, cell cycles, programmed cell death, apical dominance, fruit and ovule development, seed dormancy, and magnetoreception. Photoexcited cryptochromes interact with signaling partner proteins to alter gene expression at both transcriptional and post-translational levels and, consequently, regulate the corresponding metabolic and developmental programs[1], or via an alternative electron transport that involves small metabolites, including NADPH, NADH, and ATP. The half-life of the activated signaling state is about 16 minutes[2].
