Description

This track shows known protein-coding and non-protein-coding genes for organisms other than D. melanogaster, taken from the NCBI RNA reference sequences collection (RefSeq). The data underlying this track are updated weekly.

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).

The item labels and display colors of features within this track can be configured through the controls at the top of the track description page.

• Label: By default, items are labeled by gene name. Click the appropriate Label option to display the accession name instead of the gene name, show both the gene and accession names, or turn off the label completely.
• Codon coloring: This track contains an optional codon coloring feature that allows users to quickly validate and compare gene predictions. To display codon colors, select the genomic codons option from the Color track by codons pull-down menu. Click here for more information about this feature.
• Hide non-coding genes: By default, both the protein-coding and non-protein-coding genes are displayed. If you wish to see only the coding genes, click this box.

Methods

The RNAs were aligned against the D. melanogaster genome using blat; those with an alignment of less than 15% were discarded. When a single RNA aligned in multiple places, the alignment having the highest base identity was identified. Only alignments having a base identity level within 0.5% of the best and at least 25% base identity with the genomic sequence were kept.

Credits

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