The Introduction of the Bioinformation Center of SIBS
        Bioinformation Center was established in June of 2000. As the major biotechnological support center of the Shanghai Institutes for Biological Sciences, the Bioinformation Center has taken on a lot of key-projects and services, including the key-projects in the State 863, 973 high biotechnology plans, as well as projects from the Chinese Academy of Sciences, collaborating with other Universities and Research centers for a lot of projects in the bioinformatics researches. The center has also developed a lot biological databases and analysis softwares. At the same time, it undertakes the international collaboration and the integrated database query system – SRS package has been installed on the server in the Center. Dozens of international famous public databases, such as EMBL, NCBI, Swiss-Prot etc., have already achieved daily update. Our web site, www.biosino.org, has become one of the most important and popular web sites about bioinformatics in China.
        Up to now, the Center has two SGI Servers, one of them is SGI Altix350 system with 1.4GHz 32CPUs, 128GB Memory and 6TB RAID, another is Origin2000, 8CPUs, 8G memory, 600G RAID; a Dell PowerEdge 1750 Server 3.2GHz 10CPUs, 10G Memory, 750G RAID; three SGI 02 workstations. Blast, phrap parallel softwares have already been installed on the SGI Server. Among them, the high performance Blast software HP-BLAST is on the top for the related operation speed in national wide. There are over 40 Single, double CPUs servers, one 4 nodes, 8CPUs SGI-PC-Cluster, one 16 nodes, 32CPUs SW-Cluster in the Center, it is mainly used for the parallel, high performance and high speed SW-Blast software that we developed by ourselves. Therefore, the calculation ability and the service quality have been improved dramatically.
        The researches at our Center are much diversified, including the information integration, database development, protein structure analysis, algorithm development and application, biochip analysis, gene annotation and functional analysis, protein function and interaction prediction analysis etc. Currently, we have developed automatic text mining tool -- Smartlit, protein function and interaction prediction system: www.ddib.org. The staffs in our Center have participated in the important research projects, such as rice genome project and SARS research project, and have been as the first authors for those papers published on Nature and Science. Currently, we are studying the protein-protein interaction network in cells of human being, yeast, and Arabidopsis et al. with our developed system, combining with other information resources. With our unique systems, we can predict most of the unknown proteins’ functions and build their interaction networks; we are also developing the systems for the gene regulation network in cells. At the same time, we are building the models of the human diseases by using our systems with the experimental data. Our Center has also participated in the PSI (Proteomics Standard Initiative) of the international proteomics projects and is the major player in bioinformatics field for the international Human Liver Proteomics Project (HLPP). We have built the proteomics data management system and other related systems, and proteomics data analysis is one of our current top research fields.
