The 3′-UTR of genes has various regulatory functions including determination of messenger RNA (mRNA) stability/degradation, subcellular localization, nuclear export and translation efficiency . A class of small non-coding RNA molecules (microRNAs) bind to the 3′-UTRs of target mRNAs and mediate translational repression through the degradation of the mRNA or translational inhibition ( 11 ).

The 3' UTR is found immediately following the translation stop codon. The 3' UTR plays a critical role in translation termination as well as post-transcriptional modification. These often long sequences were once thought to be useless or junk mRNA that has simply accumulated over evolutionary time. 2012-05-01 · The 3′UTR isoforms resulting from alternative splicing and polyadenylation reflect their characteristic roles in gene expression and proteosynthesis, influencing the individual phases of the process.

The untranslated regions (UTRs) at the 3'end of mRNA transcripts contain important sequences that influence the fate of mRNA and thus proteosynthesis.

Most mRNAs have relatively short poly (A) tails at 3' UTR, usually ~20–40 nucleotides in length, when they are dormant. The molecular mechanisms involved in the extension of the poly (A) tails are another important mechanism of translational control. In the 3′ UTR of mRNAs, two cis sequences are required for polyadenylation: the cytoplasmic polyadenylation element (CPE, consensus sequence of UUUUUAU) and the hexanucleotide sequence AAUAAA, which also The 3' UTR is found immediately following the translation stop codon. The 3' UTR plays a critical role in translation termination as well as post-transcriptional modification. These often long sequences were once thought to be useless or junk mRNA that has simply accumulated over evolutionary time. However, it is now known that the untranslated region of mRNA is involved in many regulatory aspects of gene expression in eukaryotic organisms. Relative to the 5′ UTR, the DENV 3’UTR is longer (around 450 nucleotides) and lacks a poly (A) tail, but contains a number of conserved RNA structures that are essential for viral replication.

Die 3′-UTR ( 3′ untranslatierter Bereich, sprich 3-strich-UTR; englisch three prime untranslated region) ist eine Region des mRNA-Transkripts, welche sich an den für Protein codierenden Bereich anschließt. Sie beginnt hinter dem Stopcodon und reicht – in eukaryotischen Zellen – bis zum Polyadenylierungsbeginn .

3′-utr играет существенную роль в процессе маскирования мРНК.Маскирование мРНК происходит, например, в процессе оогенеза и сперматогенеза, когда синтезированные в течение этих процессов мРНК не транслируются в белок Housekeeping gene 3´UTR vectors: Housekeeping control constructs contain the 3´UTRs for common housekeeping genes cloned downstream of the RenSP luciferase reporter gene. Random control 3´UTR vectors: Random control constructs contain non-conserved, non-genic, and non-repetitive human genomic fragments. 2008-07-23 · The 3'untranslated regions of transcripts of mouse Eph receptors and ephrin ligands.

3'UTR is considered as signature of a gene. so shRNAs targetting 3'UTR. so there will be minimum off targetting. 5'UTR of the gene is not considered as signature region of the gene. so shRNA

3'UTR is considered as signature of a gene. so shRNAs targetting 3'UTR. so there will be minimum off targetting. 5'UTR of the gene is not considered as signature region of the gene. so shRNA 5' UTR，3' UTR 叫作 untranslated region ,而 introns 叫作 non-coding RNA。一段基因序列上包含外显子和内含子，转录的时候，pre-RNA就是前体RAN上会有内含子和外显子，成为成熟RNA时，内含子已经被剪切了，只保留外显子，所以内含子叫作非编码RNA（non-coding RNA）。

The 3'UTR is the region immediately after the signal for the termination of the coding region (the stop codon). The cap and the poly(A)tail mentioned in the image are added to the mRNA to prevent the mRNA from being degraded by enzymes in the cell.
