Regulation of RNA Virus Processes by Viral Genome Structure

Proceedings, 2020
The genomes of RNA viruses contain a variety of RNA sequences and structures that regulate different steps in virus reproduction. Events that are controlled by RNA elements include (i) the translation of viral proteins, (ii) the replication of viral RNA ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Function of Plant DExD/H-Box RNA Helicases Associated with Ribosomal RNA Biogenesis

Frontiers in Plant Science, 2018
Ribosome biogenesis is a highly complex process that requires several cofactors, including DExD/H-box RNA helicases (RHs). RHs are a family of ATPases that rearrange the secondary structures of RNA and thus remodel ribonucleoprotein complexes. DExD/H-box

Accurate timekeeping is controlled by a cycling activator in Arabidopsis. [PDF]

, 2013
Transcriptional feedback loops are key to circadian clock function in many organisms. Current models of the Arabidopsis circadian network consist of several coupled feedback loops composed almost exclusively of transcriptional repressors.

PICALM::MLLT10 translocated leukemia

FEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

A comparative analysis of planarian genomes reveals regulatory conservation in the face of rapid structural divergence

Nature Communications
The planarian Schmidtea mediterranea is being studied as a model species for regeneration, but the assembly of planarian genomes remains challenging.

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Cell density–dependent nuclear‐cytoplasmic shuttling of SETDB1 integrates with Hippo signaling to regulate YAP1‐mediated transcription

FEBS Letters, EarlyView.
At low cell density, SETDB1 and YAP1 accumulate in the nucleus. As cell density increases, the Hippo pathway is gradually activated, and SETDB1 is associated with increased YAP1 phosphorylation. At high cell density, phosphorylated YAP1 is sequestered in the cytoplasm, while SETDB1 becomes polyubiquitinated and degraded by the ubiquitin–proteasome ...

Small RNAs in plant defense responses during viral and bacterial interactions: similarities and differences

Frontiers in Plant Science, 2013
Small non-coding RNAs (sncRNAs) constitute an important class of gene expression regulators that control different biological processes in most eukaryotes. In plants, several small RNA silencing pathways have evolved to produce a wide range of small RNAs

Expression of the C-terminal family 22 carbohydratebinding module of xylanase 10B of Clostridium themocellum in tobacco plant [PDF]

, 2009
Carbohydrate-binding modules have been shown to alter plant cell wall structural architecture. Hence, they have the potential application of being used to engineer the plant to produce tailor-made natural fibers in the cell wall.
