Protein function
Encodes a transcription factor involved in the regulation of the circadian clock.
Phenotype
Overexpressor: ELF4 overexpressor is late flowering under LD conditions only.
[McWatters et al., 2007] Single mutant: elf4 single mutant is late flowering under both SD and LD conditions. ( The phenotype is stronger under SD than LD conditions.)
[Doyle et al., 2002][McWatters et al., 2007] Remarks: ELF4 protein interacts with GIGANTEA to sequester it from the nucleoplasm.
[Kim et al., 2013] Function:Component of the central CCA1/LHY-TOC1 feedback loop in the circadian clock that promotes clock accuracy and is required for sustained rhythms in the absence of daily light/dark cycles. Part of a corepressor complex consisting of ELF4, ELF3, and LUX involved in the transcriptional regulation of APRR9. Increases ELF3 nuclear distribution and localization in nuclear bodies. Required for responsiveness to continuous red, by regulating phytochrome B (phyB) signaling (including during seedling de-etiolation) and gene expression. Mediates both entrainment to an environmental cycle and circadian rhythm sustainability under constant conditions. Controls flowering time. Necessary for light-induced expression of both CCA1 and LHY.
