Cry2-CIB1 light-inducible binding switch
Multi-Component SwitchThe Cry2-CIB1 light-inducible binding switch is an optogenetic protein interaction module based on cryptochrome 2 and cryptochrome-interacting basic helix-loop-helix 1. In the cited work, it was integrated into a photoactivatable Tet OFF/ON system to regulate expression of a gene of interest using light illumination together with drug application.
