Bioinformatic resources for the investigation of proteins and proteomes

Abstract

Experimental techniques in omics sciences need strong support of bioinformatics tools for the data management, analysis and interpretation. Scientific community develops continuously new databases and tools. They make it possible the comparison of new experimental data with the existing ones, to gain new knowledge. Bioinformatics assists proteomics scientists for protein identification from experimental data, management of the huge data produced, investigation of molecular mechanisms of protein functions, their roles in biochemical pathways, and functional interpretation of biological processes. This article introduces the main bioinformatics resources for investigation in the protein world, with references to analyses performed by means of free tools available on the net.
