Protein function
Encodes an arginine methyltransferase.
Phenotype
Overexpressor: SKB1 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.
