An essential step for a productive infection by the dengue flavivirus (DEN) is translation of the m(7)G-capped, nonpolyadenylated positive-sense RNA genome. We have recently identified sequences within the DEN 3' untranslated region (UTR) that modulate viral translation. Here, we show that the DEN type 2 (DEN2) 3'UTR stimulated translation of m(7)G-capped DEN2 5'UTR-containing reporter mRNAs in...
Bovine spongiform encephalopathy, a member of transmissible spongiform encephalopathies, has not been reported in buffaloes, Bubalus bubalis. Prion protein (PrP), encoded by the prion protein gene (PRNP), is fundamental in the pathogenesis of transmissible spongiform encephalopathies. We previously showed that buffaloes express more PrP proteins but lower PRNP mRNA than cattle in several pivota...
The glutamate receptor 2 (GluR2) subunit determines many of the functional properties of the alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate subtype of glutamate receptor. The roles of untranslated regions (UTRs) in mRNA stability, transport, or translation are increasingly recognized. The 3' end of the GluR2 transcripts are alternatively processed to form a short and long 3'UTR, giving ri...
BACKGROUND MicroRNA are a class of small RNAs that regulate gene expression by inhibiting translation of protein encoding transcripts through targeting of a microRNA-protein complex by base-pairing of the microRNA sequence to cognate recognition sequences in the 3' untranslated region (UTR) of the mRNA. Target identification for a given microRNA sequence is generally accomplished by informatics...
The 3' untranslated genome region (UTR) of arthropod-borne viruses is characterized by enriched direct repeats (DRs) and stem-loop structures. Despite many years of theoretical and experimental study, on-going positive selection on the 3'UTR had never been observed in 'real-time,' and the role of the arbovirus 3'UTR remains poorly understood. We observed a lineage-specific 3'UTR sequence patter...
BACKGROUND Mature microRNAs (miRNAs) are single-stranded RNAs that regulate post-transcriptional gene expression. In our previous study, we have shown that versican 3'UTR, a fragment of non-coding transcript, has the ability to antagonize miR-199a-3p function thereby regulating expression of the matrix proteins versican and fibronectin, and thus resulting in enhanced cell-cell adhesion and orga...
The presence of regulatory sequences in the 3' untranslated region (3'-UTR) of eukaryotic mRNAs controlling RNA stability and translation efficiency is widely recognized. In contrast, the relevance of 3'-UTRs in bacterial mRNA functionality has been disregarded. Here, we report evidences showing that around one-third of the mapped mRNAs of the major human pathogen Staphylococcus aureus carry 3'...
The 3' untranslated region (UTR) is usually involved in the switch of the translation and replication for a positive-sense RNA virus. To understand the 3' UTR involved in an internal ribosome entry site (IRES)-mediated translation in Classical swine fever virus (CSFV), we first confirmed the predicted secondary structure (designated as SLI, SLII, SLIII, and SLIV) by enzymatic probing. Using a r...
IFITM3 is interferon-induced transmembrane 3, which plays an extremely key role in anti-proliferation, anti-virus and anti-tumor diseases. In this study, the yak (Bos grunniens) (BgIFITM3) gene contained a 5′-untranslated region (UTR) (25 bp), coding (441 3′-UTR (115 bp). The expression of BgIFITM3 liver was significantly higher than that heart, spleen, lung kidney (P < 0.01). protein localized...
