The role of the 5′ untranslated regions of Potyviridae in translation

Virus Research, 2015
The Potyviridae family relies on a cap-independent translation mechanism to facilitate protein expression. The genomic architecture of the viral RNAs of the Potyviridae family resembles those of the animal picornaviruses. The viral genomes lack a 5' cap structure. Instead, they have the viral protein VPg covalently linked to the 5' end of the RNA.

The small genome segment of Bunyamwera orthobunyavirus harbours a single transcription-termination signal [PDF]

, 2012
Transcription termination of the mRNA produced from the small (S) genome segment of Bunyamwera orthobunyavirus (BUNV) has previously been mapped to two cis-acting sequences located within the 5′ UTR using a virus-free replication assay.

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

Advanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

U4 at the 3' UTR of PB1 segment of H5N1 influenza virus promotes RNA polymerase activity and contributes to viral pathogenicity.

PLoS ONE, 2014
The viral RNA-dependent RNA polymerase has been found to contribute to efficient replication in mammalian systems and to the high pathogenicity of H5N1 influenza A virus in humans and other mammals. The terminal untranslated regions of the viral segments

Fine‐Tuned Regulation of mRNA Translation and Transport by STAU2 Condensate Facilitates Neuronal Development and Plasticity

Advanced Science, EarlyView.
STAU2 undergoes phase separation to form dynamic condensates that package target mRNAs and deliver them to the distal ends of growing neuronal dendrites. STAU2 condensates stabilize embedded mRNAs and repress their translation. Synaptic activity bidirectionally remodels STAU2 condensates, coordinating local translation of STAU2‐associated mRNAs ...

Genetic predisposition to porto‐sinusoidal vascular disorder: A functional genomic‐based, multigenerational family study

Hepatology, EarlyView., 2022
A deleterious variant of FCHSD1 results in mTOR pathway overactivation and may cause porto‐sinusoidal vascular disorder (PSVD). The pedigree of the family demonstrated an autosomal dominant disease with variable expressivity. Whole‐genome sequencing and Sanger sequencing both validated the existence of the FCHSD1 variant and the heterozygosity of c ...

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

Advanced Science, EarlyView.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes

Advanced Science, EarlyView.
A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...
