This track contains tBLASTn alignments of the peptides from the predicted and known genes identified in the hg18 Known Genes track as of 13 Feb 2006. Since the release of the hg18 "UCSC Genes" track in March, 2007, which also contains non-protein-coding genes, the data underlying this track are displayed in the hg18 track "Old Known Genes"
