Exploring relationships and mining data with the UCSC Gene Sorter

In parallel with the human genome sequencing and assembly effort, many tools have been developed to examine the structure and function of the human gene set. The University of California Santa Cruz (UCSC) Gene Sorter has been created as a gene-based Counterpart to the chromosome-oriented UCSC Genome Browser to facilitate the Study of gene function and evolution. This simple, but powerful tool provides a graphical display of related genes that call be sorted and filtered based oil a variety of criteria. Genes may be ordered based oil Such characteristics as expression profiles, proximity ill genome, shared Gene Ontology (GO) terms, and protein similarity. The display call be restricted to a gene set meeting a specific set of constraints by filtering on expression levels, gene name or ID, chromosomal position, and so oil. The default set of information for each gene entry-gene name, selected expression data, a BLASTP E-value, genomic position, and a description-can be configured to include many other types of data, inducing expanded expression data, related accession numbers and IN, orthologs ill other species, GO terms, and much more. The Gene Sorter, a CGI-based Web application written in C with a MySQL database, is tightly integrated with the other applications in the UCSC Genome Browser Suite. Available oil a selected subset of the genome assemblies found in the Genome Browser, it further enhances the usefulness of the UCSC tool set ill interactive genomic exploration and analysis.
