GSE84068: Post-transcriptional 3UTR cleavage of mRNA transcripts generates thousands of stable uncapped autonomous RNA fragments

• Organsim human
• Type RNASEQ
• Target gene
• Project ARCHS4

Here, using genome wide analysis, we demonstrate that canonical mRNA is processed post-transcriptionally through an alternative cleavage and polyadenylation mechanism. As a result of this process, the downstream cleavage fragment of the 3UTR remains uncapped and stable; This finding indicates that different parts of gene mRNA are separate and independent, by re-annotating the human transcriptome using this model, we provide a new overview of the function and impact of microRNA (miRNA); Our results shed new light on the mammalian transcriptome and show that what were considered as 3UTRs are in fact autonomous RNA fragments.
