Webmotif. The ultraconserved elements associated with alternative splicing events often contain small coding exons that are skipped in the mRNA in some tissues, but the elements extend well into the flanking intronic regions on one or both sides of the exon. Such is the case for one explicitly studied ultraconserved element (uc.33) in PTBP2, a WebThe existence of ultraconserved elements in the human genome that do not code for protein provides evidence that _____. many genomic regions outside of protein-coding genes are functional.
