== Publication Abstract from PubMed ==
We determined the three-dimensional structure of the PHD finger of the rice Siz/PIAS-type SUMO ligase, OsSiz1, by NMR spectroscopy and investigated binding ability for a variety of methylated histone H3 tails, showing that OsSiz1-PHD primarily recognizes dimethylated Arg2 of the histone H3 and that methylations at Arg2 and Lys4 reveal synergy effect on binding to OsSiz1-PHD. The K4 cage of OsSiz1-PHD for trimethylated Lys4 of H3K4me3 was similar to that of the BPTF-PHD finger, while the R2 pocket for Arg2 was different. It is intriguing that the PHD module of Siz/PIAS plays an important role, with collaboration with the DNA binding domain SAP, in gene regulation through SUMOylation of a variety of effectors associated with the methylated arginine-riched chromatin domains.
