CC -!- FUNCTION: Transcription factor acting positively in the CC phytochrome signaling pathway. Activates transcription by binding CC to the G box (5'-CACGTG-3'). CC -!- SUBUNIT: Homodimer (Probable). Can form a heterodimer with REP1 CC and PIF4. Phytochrome B binds specifically to DNA-bound PIF3, but CC only upon red light induced conversion to the Pfr form (PfrB). CC Reconversion to Pr form causes rapid dissociation. Interacts with CC APRR1/TOC1.

CC -!- INDUCTION: By UV treatment. CC -!- SIMILARITY: Contains 1 basic helix-loop-helix (bHLH) domain.
