Description

The RefSeq Genes track shows known protein coding genes taken from mRNA reference sequences compiled at LocusLink. Coding exons are displayed taller than 5' and 3' untranslated regions (UTR). Connecting introns are one-pixel lines with hatch marks indicating direction of transcription. Non-coding RNA genes have their own track in some assemblies.

Method

Refseq mRNAs are aligned against the genome using the BLAT program. When a single mRNA aligns in multiple places only the best alignments are kept. The alignments must also have at least 96% sequence identity to be kept.

Credits

The RefSeq Genes track is produced at UCSC from mRNA sequence data generated by scientists worldwide and curated by the RefSeq project at NCBI.
