Circadian clock overview

Protein function

Encodes a transcription factor involved in circadian clock and phytochrome regulation.

Phenotype

Overexpressor:
CCA1 overexpressor is late flowering under both SD and LD conditions. [Lu et al., 2012][Wang et al., 1998]

Single mutant:
cca1 single mutant is slightly early flowering under SD conditions only. [Mizoguchi et al., 2002]

Multiple mutant:
lhy;cca1 multiple mutant is early flowering under both SD and LD conditions. [Fujiwara et al., 2008][Mizoguchi et al., 2002]

Remarks:
CCA1 is partially redundant with LHY and controls SVP protein accumlulation. [Fujiwara et al., 2008][Mizoguchi et al., 2002]

Function:
Transcription factor involved in the circadian clock and in the phytochrome regulation. Binds to the promoter regions of APRR1/TOC1 and TCP21/CHE to repress their transcription. Binds to the promoter regions of CAB2A and CAB2B to promote their transcription. Represses both LHY and itself. [Data from UniProt]
