Protein function

Encodes a structural core component of a COMPASS-like H3K4 histone methylation complex.

Phenotype

Remarks:
ASH2R encodes a structural core component of the COMPASS-like complex, which is involved in the positive regulation of FLC expression. Thus, ASH2R overexpression results in increased FLC expression level. [Jiang et al., 2011]

Single mutant:
ash2r homozygous mutant is not viable. [Jiang et al., 2011]

Overexpressor:
ASH2R overexpressor is late flowering under LD conditions. ( No data under SD conditions.) [Jiang et al., 2011]

RNA interference:
RNAi downregulation of ASH2R leads to early flowering under LD conditions. ( No data under SD conditions.) [Jiang et al., 2011]

Function:
Trithorax-group gene homolog required for early embryogenesis (PubMed:20118203, PubMed:21423667). Required for the expression of FLC and FLC homologs and represses flowering (PubMed:21423667). Required for proper leaf growth and development (PubMed:21423667). Part of COMPASS-like complexes responsible for H3K4 trimethylation, but not for di- or mono-methylation of histone H3 Lys-4 (PubMed:21423667). Binds to target loci chromatin, increasing H3K4 trimethylation and causing activation of the gene (PubMed:21423667). [Data from UniProt]
