Protein function
Encodes a transcription factor involved in the regulation of the circadian clock.
Phenotype
Remarks: elf3-1 single mutant is phototoperiod-insensitive, misexpresses
GIGANTEA, and flowers at the same time under both SD and LD conditions.
[Liu et al., 2001][Fowler et al., 1999] Overexpressor: ELF3 overexpressor is late flowering under LD conditions only.
[Liu et al., 2001] Single mutant: elf3 single mutant is early flowering under both SD and LD conditions.
[Lu et al., 2012][Liu et al., 2001][Zagotta et al., 1996] Function:May be a transcription factor part of a circadian clock input pathway. Acts within a zeitnehmer feedback loop and is involved in its own circadian regulation. Has no role in regulating circadian clock function in the dark. Part of a corepressor complex consisting of ELF4, ELF3, and LUX involved in the transcriptional regulation of APRR9. The activity of the protein may be decreased in long day conditions due to its interaction with phytochrome B (phyB). Can regulate the initiation of flowering independently of phyB. Also involved in responses to nematode parasitism, like the formation of the nematode feeding structure.
