Large-scale phosphorylation mapping reveals the extent of tyrosine phosphorylation in Arabidopsis.

A team of IAB and RIKEN researchers published this week that they identified on a large-scale, phosphorylation sites of Arabidopsis proteins.  Most cellular processes in Arabidopsis, a widely-used plant model, are likely to be regulated at least in part by various phosphorylation events which appear strikingly similar to the human phosphoproteome profile.  The results are published in Molecular Systems Biology (6 May 2008. 4: 193 doi:10.1038/msb.2008.32). The research group consists of the following researchers; Dr. Yasushi Ishihama of IAB, Dr. Naoyuki Sugiyama, Leader of Biomedical Group at Human Metabolome Technologies,Inc., Dr. Ken Shirasu, Group Director and Dr. Hiroshi Nakagami, Research Scientist of Plant Immunity Research Group at RIKEN Plant Science Center.
