TOOLS FOR PREDICTION AND ANALYSIS OF PROTEIN-CODING GENE STRUCTURE

CpG islands prediction





MOTIVATION

         Prediction of protein-coding genes in newly sequenced DNA becomes very important in large genome sequencing projects. This problems is complicted due to exon-intron of the eukaryotic genes. CpG islands are important signature of 5' region of many mammalian genes.

RESULTS

         The WWWCPG program locates CpG islands as defined by Gardiner-Garden M. and Frommer M. (CpG islands in vertebrate genomes, J.Mol.Biol, 1987, 196, 261-276): these are regions greater than 200 bp in length which have more than 50% G+C (p(G)+p(C) > 0.5) and have a CpG content of at least 0.6 of that expected on the basis of the G+C content of the region (p(CpG) > 0.6*p(C)*p(G)).
