CGCV :: BLAST

Dynamic Gene Cluster Comparison in Eukaryotic Genomes

Are you curious how a gene cluster is conserved across other eukaryotic genomes? Use our web-based Comparative Gene Cluster Viewer (CGCV) to interactively visualize the conservation of your favorite gene cluster against protein sequences from the selected species via our novel multi-genome browser. Step-by-step instructions are provided in the tutorial page.
