The 5′ untranslated region (also known as 5′ UTR, leader sequence, transcript leader, or leader RNA) is the region of a messenger RNA (mRNA) that is directly...

single-stranded RNA molecules with an untranslated region (UTR) at the 5′ end which is called the 5′ UTR. The 5′ UTR is responsible for important biological functions...

the 5'UTR and 3'UTR which result in the cyclisation of the viral RNA, which is essential for viral replication. The 3'UTRs are typically 0.3–0.5 kb in...

Flavivirus 5' UTR are untranslated regions in the genome of viruses in the genus Flavivirus. The Flavivirus positive-oriented, single-stranded RNA genome...

UTR) refers to either of two sections, one on each side of a coding sequence on a strand of mRNA. If it is found on the 5' side, it is called the 5'...

untranslated region (3′-UTR) is the section of messenger RNA (mRNA) that immediately follows the translation termination codon. The 3′-UTR often contains regulatory...

Tombusvirus 5′ UTR is an important cis-regulatory region of the Tombus virus genome. Tomato bushy stunt virus is the prototype member of the Tombusviridae...

which is downregulated in NPCs, and by MeCP2 and methylation of the L1 5' UTR. Human cell lines modeling the neurological disorder Rett syndrome, which...

sequence, but exons containing only regions of 5′-UTR or (more rarely) 3′-UTR occur in some genes, i.e. the UTRs may contain introns. Some non-coding RNA transcripts...

protein translation. The stability of mRNAs may be controlled by the 5' UTR and/or 3' UTR due to varying affinity for RNA degrading enzymes called ribonucleases...
