Description

The All-Drosophila RefSeq Genes track shows known protein coding genes for all Drosophila species taken from mRNA reference sequences compiled at LocusLink. Coding exons are represented by blocks connected by horizontal lines representing introns. The 5' and 3' untranslated regions (UTRs) are displayed as shorter blocks on the leading and trailing ends of the aligning regions. In full display mode, arrowheads on the connecting intron lines indicate the direction of transcription.

Method

Refseq mRNAs for all Drosophila species are aligned against the genome using the blat program. blat is run in translated mode. When a single mRNA aligns in multiple places, only the best alignments which also have at least 25% sequence identity and cover at least 30% of the mRNA are kept.

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