...cyan light, Dronpa dimers dissociate, Dronpa goes dark, and MEK1 is active or “on.” Dronpa’s color thus... the Dronpa dimers interact and lock MEK1 in an “off” setting by blocking the active site. Dronpa also...Additionally, dimeric Dronpa is less prone to aggregation in cells compared to the tetrameric Dronpa it was derived...status of MEK1/2 was tracked at 5 minute intervals via Western blot. Phosphorylation of MEK1/2 peaks at just... phosphorylated MEK1/2 levels, suggesting PP1/PP2A is responsible for this MEK1/2 negative feedback.
