1. SSP (Mirror 1; Mirror 2): A genome-wide analysis of sumoylation-related biological processes and functions in human nucleus. Totally 2,683 potential SUMO substrates conserved in both human and mouse were identified. And we design a simple query software to search the results.

2. SUMOsp: Highly accurate software for prediction of sumoylation site.

3. GPS: one of our recent projects. We designed a novel algorithm GPS (Group-based Phosphorylation sites Prediction) and construct an easy-to-use web server for the experimentalists.

4. PPSP: Prediction of PK-Specific Phosphorylation site. The software has been implemented in Bayesian Decision Theory (BDT) algorithm.

5. MeMo: The first computational program for prediction of protein methylation site on either lysine or arginine residues.

6. Two mirror sites of this database are deposited in LCD USTC, and CSBL UGA.
