Abstract:Three-prime untranslated regions (3'UTRs) of metazoan mRNAs contain numerous regulatory elements, yet remain largely uncharacterized. Using polyA capture, 3'RACE, full-length cDNAs, and RNA-seq, we define ~26,000 distinct 3'UTRs in Caenorhabditis elegans for ~85% of the 18,328 experimentally supported protein coding genes and revise ~40% of gene models. Alternative 3'UTR isoforms are frequent, often differentially expressed during development. Average 3'UTR length decreases with animal age. Surprisingly, no polyadenylation signal (PAS) is detected for 13% of polyA sites, predominantly among shorter alternative isoforms. Trans-spliced (vs. non-trans-spliced) mRNAs possess longer 3'UTRs and frequently contain no PAS or variant PAS. We identify conserved 3'UTR motifs, isoform-specific predicted microRNA target sites, and polyadenylation of most histone genes. Our data reveal a rich complexity of 3'UTRs genome-wide and throughout development.
