We wish to understand different mechanisms governing the activities of COP1 and LRBs with respect to CRY2 ubiquitination. Most presently known light-dependent CRY2-interacting proteins interact with the photon-sensing PHR domain of CRY23. However, COP1 is one of the few exceptions. COP1 binds to the … See more We have previously shown that the blue light-dependent ubiquitination and proteolysis of CRY2 is diminished but not completely abolished in the cop1 null mutant22, suggesting the existence of another E3 ubiquitin … See more To test whether the Cul3LRBs and Cul4COP1/SPAs E3 ubiquitin ligases catalyze blue light-dependent CRY2 ubiquitination, we performed three independent experiments. In the first two experiments, we … See more We next tested how LRBs regulate cryptochrome activity by examining the blue light-dependent degradation of CRY2 in the lrb123 mutants.

WebOct 1, 2012 · In blue light, cry1 interacts with SPA1 and sequesters it from COP1, thereby probably disrupting the COP1–SPA1 complex that is important for E3 function. COP1 also interacts with cry1 in a light-independent manner (not shown here). Visible light further promotes the nuclear export of COP1 for long-term suppression of COP1.
