Characterization of the PRMT gene family in rice reveals conservation of arginine methylation.

ABSTRACT: Post-translational methylation of arginine residues profoundly affects the structure and functions of protein and, hence, implicated in a myriad of essential cellular processes such as signal transduction, mRNA splicing and transcriptional regulation. Protein arginine methyltransferases (PRMTs), the enzymes catalyzing arginine methylation have been extensively studied in animals, yeast and, to some extent, in model plant Arabidopsis thaliana. Eight genes coding for the PRMTs were identified in Oryza sativa, previously. Here, we report that these genes show distinct expression patterns in various parts of the plant. In vivo targeting experiment demonstrated that GFP-tagged OsPRMT1, OsPRMT5 and OsPRMT10 were localized to both the cytoplasm and nucleus, whereas OsPRMT6a and OsPRMT6b were pred
