This track shows alignments of $organism mRNAs from the Mammalian Gene Collection (MGC) having full-length open reading frames (ORFs) to the genome. Coding exons are represented by blocks connected by horizontal lines representing introns. The 5' and 3' untranslated regions (UTRs) are displayed as thinner 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.
GenBank $organism MGC mRNAs identified as having full-length ORFs are aligned against the genome using the blat program. When a single mRNA aligns in multiple places, the alignment having the highest base identity is found. Only alignments that have a base identity level within 1% of the best and also have at least 95% base identity are kept.
The $organism MGC full-length mRNA track is produced at UCSC from mRNA sequence data submitted to GenBank by the Mammalian Gene Collection project.
