This track displays NISC-generated, curated gene annotations for the human genome and each of the selected species. Coding exons are depicted taller than 5' and 3' untranslated regions (UTR). Connecting introns are one-pixel lines with hatch marks indicating direction of transcription.
Exon locations of known genes were determined by aligning human and/or mouse reference cDNA sequences with the assembled genomic sequence of each species. When splice site consensus, exon structure, or protein translation errors were encountered, they were manually inspected and corrected.
Thanks to Pamela Jacques Thomas from NHGRI for providing these curated gene annotations.
