Protein function
Encodes a subunit of the Paf1c complex.
Phenotype
Remarks: PHP encode a subunit of the Paf1 complex, which is involved in the positive regulation of
FLC expression.
php single mutant has reduced
FLC expression levels.
[Yu et al., 2010][Park et al., 2010] Single mutant: php single mutant is early flowering under both SD and LD conditions.( The flowering-time phenotype is stronger in the Col
FRI than in the Col-0 background.)
[Yu et al., 2010][Park et al., 2010] Function:Component of the PAF1 complex (PAF1C) which is involved in histone modifications such as methylation on histone H3 Lys-4 (H3K4me3) (PubMed:20363855). Involved in regulation of flowering time. Required for the expression of the flowering repressors FLC and MADS-box genes of the MAF family. Required for histone H3 trimethylation on Lys-4 H3K4me3 at the FLC locus (PubMed:20363855, PubMed:20463090). Prevents trimethylation on Lys-27 H3K276me3 at the same locus (PubMed:20363855).
