The hg18 Gene Sorter has been expanded to include the Wanker (37), Vidal (38) and Human Protein Reference Database (39) data sets showing the neighborhood of protein interactions surrounding selected genes. The neighborhoods are computed from a genome-wide protein–protein interaction network that connects genes if the proteins they encode have been detected to physically interact in high-throughput experiments. The xxBlastTab tables, which display gene ortholog data for human, mouse and rat in the Gene Sorter and UCSC Genes details pages, have now been filtered for synteny.
