PRR9, PRR7, and PRR5 proteins are major transcriptional repressors of CCA1 and LHY and are thus essential for proper clock function.
Title: PSEUDO-RESPONSE REGULATORS 9, 7, and 5 are transcriptional repressors in the Arabidopsis circadian clock.
findings show that the overexpression of PRR7 leads to severely compromised circadian rhythms & that the PRR7 protein is phosphorylated in a circadian regulated manner & its levels are post-translationally regulated by both diurnal & circadian mechanisms
Title: PRR7 protein levels are regulated by light and the circadian clock in Arabidopsis.
