Milanesi Luciano Catania, Italy 13/03/ Introduction Bioinformatics applications have become an ideal research area where computer scientists can apply and further develop new intelligent computation methods, in both experimental and theoretical cases. Bioinformatics needs –Data storage (sequencing, genotyping, microarray) –Connection with HPC infrastructure –Data sharing and distribution The European Bioinformatics initiative based on infrastructure created by the EGEE and BioinfoGRID try to address these issues. - 2 years: 1 Gen 2006 – 31 Dic 2007

Milanesi Luciano Catania, Italy 13/03/ BioinfoGRID Project The BIOINFOGRID project aims to –promote the Bioinformatics Grid application for life science in the bioinformatics community –Evaluate and adopt high-level user interfaces –Evaluate bioinformatics applications in five main fields  Genomics, Proteomics, Transcriptomics, Molecular dynamics, Biological database Partners

Milanesi Luciano Catania, Italy 13/03/ Molecular applications in GRID Aim : The objective is to docking and Molecular Dynamics simulations, which usually take a very long time to complete the analysis. Description Wide In Silico Docking On Malaria initiative WISDOM- II:This project perform the docking and molecular dynamics simulation on the GRID platform for discovery new targets for neglected diseases. Analysis can be performed notably using the data generated by the WISDOM application on the EGEE infrastructure.

Milanesi Luciano Catania, Italy 13/03/ Influenza A Neuraminidase Grid-enabled High-throughput in-silico Screening against Influenza A Neuraminidase Encouraged by the success of the first EGEE biomedical data challenge against malaria (WISDOM), the second data challenge battling avian flu was kicked off in April 2006 to identify new drugs for the potential variants of the Influenza A virus. In this project, the impact of a world-wide Grid infrastructure to efficiently deploy large scale virtual screening to speed up the drug design process has been demonstrated.
