Protein function
Encodes a H3K4 demethylase that represses the expression of
FT and
TSF.
Phenotype
Single mutant: jmj14 single mutant is early flowering under both SD and LD conditions.
[Lu et al., 2010][Yang et al., 2010][Jeong et al., 2009][Searle et al., 2010] Remarks: JMJ14 represses the expression of
FT and
TSF.
[Lu et al., 2010][Yang et al., 2010][Jeong et al., 2009] Function:Histone demethylase that demethylates Lys-4 (H3K4me) of histone H3 with a higher activity for H3K4me3 and H3K4me2 than H3K4me1. No activity on H3K9me3/2, H3K36me3/2 and H3K27me3/2. Represses FT and TSF expression to inhibit the floral transition. Binds around the transcription start site of the FT locus. Involved in the DRM2-mediated maintenance of DNA methylation, but not required for the de novo DNA methylation. Required for demethylating histone H3K4me3 at the target of RNA silencing.
