Human protein arginine methyltransferase 5 encodes a type Ⅱ protein arginine methyltransferase and its orthologs in animals and yeast have been shown to play important roles in the regulation of RNA processing,signal transduction and gene expression.However,PRMT5 homologs in higher plants have not yet been reported and biological significance of these proteins in plant development remains elusive.Here,using conventional biochemical approach,we purified a plant histone arginine methyltransferase from cauliflower that was nearly identical to AtPRMT5,an Arabidopsis homolog of human PRMT5.AtPRMT5 symmetrically di-methylated histone H4R3,H2A and myelin basic protein (MBP) in vitro.
