Search tips

Please note, the name searching system is not completely case insensitive. When in doubt, enter search names in all lower case to find gene names.

Methods

The mRNAs were aligned against the mouse (Jun. 2020 (GRCm39/mm39)) genome using translated blat. When a single mRNA aligned in multiple places, the alignment having the highest base identity was found. Only those alignments having a base identity level within 1% of the best and at least 25% base identity with the genomic sequence were kept.

Specifically, the translated blat command is: 

blat -noHead -q=rnax -t=dnax -mask=lower target.fa query.fa target.query.psl

where target.fa is one of the chromosome sequence of the genome assembly,
and the query.fa is the mRNAs from RefSeq
The resulting PSL outputs are filtered: 
pslCDnaFilter -minId=0.35 -minCover=0.25  -globalNearBest=0.0100 -minQSize=20 \
  -ignoreIntrons -repsAsMatch -ignoreNs -bestOverlap \
    all.results.psl mm39.xenoRefGene.psl
The filtered mm39.xenoRefGene.psl is converted to genePred data to display for this track.

Credits

The mRNA track was produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
