DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics
Advanced Science, EarlyView.This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

Monitoring helicase activity with molecular beacons
BioTechniques, 2008 A high-throughput, fluorescence-based helicase assay using molecular beacons is described. The assay is tested using the NS3 helicase encoded by the hepatitis C virus (HCV) and is shown to accurately monitor helicase action on both DNA and RNA.

Mtr4 RNA helicase structures and interactions
Biological Chemistry, 2021 Abstract Mtr4 is a Ski2-like RNA helicase that plays a central role in RNA surveillance and degradation pathways as an activator of the RNA exosome. Multiple crystallographic and cryo-EM studies over the past 10 years have revealed important insight into the Mtr4 structure and interactions with protein and nucleic acid binding partners ...

Advanced Science, EarlyView.This study identifies SNRPF as a critical oncogenic driver in ovarian cancer. By regulating a self‐sustaining SNRPF–DDX24–E2F4 feedback loop through intron retention and nonsense‐mediated decay, SNRPF couples RNA splicing with transcriptional regulation to promote tumor progression.

Advanced Science, EarlyView.Molecular, genetic, virological, and biochemical analysis in combination with global proteome and phosphoproteome profiling and functional assays were applied to study the role of PR130 in the context of HSV‐1 replication. The observations reveal that host‐intrinsic mechanisms regulate HSV‐1 replication and highlight PR130 as a susceptibility factor of

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.

Modulation of MCM Helicase activity [PDF]
, 2011 The minichromosome maintenance (MCM) proteins are essential for the initiation and progression of DNA replication. MCMs are believed to function as the replicative helicase in archaea and eukaryotes.

Membrane recognition and dynamics of the RNA Degradosome [PDF]
, 2015 RNase E, which is the central component of the multienzyme RNA degradosome, serves as a scaffold for interaction with other enzymes involved in mRNA degradation including the DEAD-box RNA helicase RhlB.
