AS Transcript Navigator. a Screen shot of transcript models for the ACSM2B gene as an example. This gene is transcribed into three mRNAs, comprising 16 distinct exons in total. Blocks and lines indicate exons and introns. Among exon blocks, the thicker blocks are coding regions (CDS), and thinner blocks are untranslated regions (UTRs). AS Transcript Navigator contains tracks of exon usage, SNPs, Met, and miRNAs within the defined transcribed region of a gene. Exon usage is composed of the representative exons, clustered according to the genomic location of overlapping exons. The SNP, Met, and miRNA tracks represent their respective locations. Transcripts in the mRNA coordinate when the intron scale is 0% (a), and both exons and introns are equivalent in the genome browser when the intron scale is 100% (b)
