Structural exon database, SEDB, mapping exon boundaries on multiple protein structures

Comparative analysis of exon/intron organization of genes and their resulting protein structures is important for understanding evolutionary relationships between species, rules of protein organization and protein functionality. We present Structural Exon Database (SEDB), with a Web interface, an application that allows users to retrieve the exon/intron organization of genes and map the location of the exon boundaries and the intron phase onto a multiple structural alignment. SEDB is linked with Friend, an integrated analytical multiple sequence/structure viewer, which allows simultaneous visualization of exon boundaries on structure and sequence alignments. With SEDB researchers can study the correlations of gene structure with the properties of the encoded three-dimensional protein structures across eukaryotic organisms.
