This track shows known protein-coding genes from organisms other than $organism, taken from the NCBI mRNA reference sequences collection (RefSeq).
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). In some assemblies, non-coding RNA genes are shown in a separate track.
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.
The mRNAs were aligned against the mouse genome using blat; those with an alignment of less than 15% were discarded. At least 40 bases must be aligned to DNA that is not repeat masked. When a single mRNA aligned in multiple places, the alignment having the highest base identity was identified. Only alignments having a base identity level within 1.0% of the best and at least 35% base identity with the genomic sequence were kept.
This track was produced at UCSC from mRNA sequence data generated by scientists worldwide and curated by the NCBI RefSeq project.
