## Description

The All-Drosophila RefSeq Genes track shows known protein-coding genes for all Drosophila species taken from the NCBI mRNA reference sequences collection (RefSeq).

## Display Conventions and Configuration

This track follows the display conventions for gene prediction tracks. The color shading indicates the level of review the RefSeq record has undergone: predicted (light), provisional (medium), reviewed (dark).

## Methods

Refseq mRNAs for all Drosophila species were aligned against the genome using blat in translated mode. When a single mRNA aligned in multiple places, only the best alignments that had at least 25% sequence identity and covered at least 30% of the mRNA were kept.

## Credits

This track was produced at UCSC from mRNA sequence data generated by scientists worldwide and curated by the NCBI RefSeq project.
