3′ Untranslated region (3′ UTR)

3′ untranslated region (3′ UTR)

The transcribed portion of an mRNA after its coding sequence that can influence RNA stability, location, and translation.

Overview

EXPLORE BY LEVEL

The 3′ UTR is a section at the end of many messenger RNAs. It is not translated into the protein, but it can help control how long the message lasts, where it goes, and how often it is read.

Research Claims

3′ UTR length and sequence vary with alternative polyadenylation and transcript isoforms. Regulatory interactions are context dependent and cannot generally be inferred from a short motif alone.
