NCBI Protein Information
EARLY FLOWERING-like protein (DUF1313)
NCBI Summary
Encodes a novel nuclear 111 amino-acid phytochrome-regulated component of a negative feedback loop involving the circadian clock central oscillator components CCA1 and LHY. ELF4 is necessary for light-induced expression of both CCA1 and LHY, and conversely, CCA1 and LHY act negatively on light-induced ELF4 expression. ELF4 promotes clock accuracy and is required for sustained rhythms in the absence of daily light/dark cycles. It is involved in the phyB-mediated constant red light induced seedling de-etiolation process and may function to coregulate the expression of a subset of phyB-regulated genes.

UniProt Comments
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.
