Encodes an arginine methyltransferase.
overexpressor is early flowering under LD conditions. ( No data available under SD conditions.) [Wang et al., 2007] Remarks: skb1
single mutant has increased FLC
expression levels. [Wang et al., 2007][Schmitz et al., 2008] Single mutant: skb1
single mutant is late flowering under both SD and LD conditions. [Wang et al., 2007][Pei et al., 2007][Schmitz et al., 2008][Schmitz et al., 2008][Zhang et al., 2011] Function:
Methylates arginine residues of myelin basic protein (MBP) in vitro. Methylates symmetrically histone H4 of the FLC chromatin to form H4R3me2s, which in turn suppresses FLC expression to induce flowering. Regulates alternative splicing by methylating spliceosomal proteins. Involved in the post-transcriptional regulation of the circadian clock. [Data from UniProt]
