Domains required for the interaction of the central negative element FRQ with its transcriptional activator WCC within the core circadian clock of Neurospora.

Abstract excerpt

In the negative feedback loop composing the Neurospora circadian clock, the core element, FREQUENCY (FRQ), binds with FRQ-interacting RNA helicase (FRH) and casein kinase 1 to form the FRQ-FRH complex (FFC) which represses its own expression by interacting with and promoting phosphorylation of its transcriptional activators White Collar-1 (WC-1) and WC-2 (together forming the White Collar complex, WCC).
