Helicases at Work: The Importance of Nucleic Acids Unwinding Under Cold Stress

DNA
Separation of duplex strands of nucleic acids is a vital process in the nucleic acid metabolism and survival of all living organisms. Helicases are defined as enzymes that are intended to unwind the double-stranded nucleic acids.

Terminating the replication helicase

Nature Cell Biology, 2017
A feature of the cell cycle is that the events of one cycle must be reset before the next one begins. A study now shows that the replication machinery is removed from fully replicated DNA by a conserved ubiquitin- and CDC48 (also known as p97)-dependent pathway. This explains how eukaryotic chromosomes are returned to the unreplicated state.

Disentangling Heterogeneous Molecular Networks for Multi‐Omics‐Driven Cancer Driver Discovery

Advanced Science, EarlyView.
DRIVE integrates PPI topology and pan‐cancer multi‐omics profiles through dual‐view graph disentanglement, contrastive representation learning, and joint optimization. Across six PPI networks, DRIVE outperforms ten baselines and remains robust to structural and annotation perturbations.

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

Advanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

Structural basis of Zika virus helicase in recognizing its substrates

Protein & Cell, 2016
The recent explosive outbreak of Zika virus (ZIKV) infection has been reported in South and Central America and the Caribbean. Neonatal microcephaly associated with ZIKV infection has already caused a public health emergency of international concern.

The RNA helicase Rm62 cooperates with SU(VAR)3-9 to re-silence active transcription in Drosophila melanogaster. [PDF]

, 2011
Gene expression is highly dynamic and many genes show a wide range in expression over several orders of magnitude. This regulation is often mediated by sequence specific transcription factors.

Spinal Involvement in Charge Syndrome: Implications for Management

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT CHARGE syndrome (OMIM #214800) is an autosomal dominant disorder caused by mutations in the CHD7 gene in most cases. Although originally defined by the CHARGE acronym (coloboma, heart defects, choanal atresia, growth restriction, genital hypoplasia, and ear anomalies), the recognized phenotype has expanded considerably to include highly ...

Dissociation of Rad51 Presynaptic Complexes and Heteroduplex DNA Joints by Tandem Assemblies of Srs2

Cell Reports, 2017
Srs2 is a superfamily 1 (SF1) helicase and antirecombinase that is required for genome integrity. However, the mechanisms that regulate Srs2 remain poorly understood.

A prominent β-hairpin structure in the winged-helix domain of RECQ1 is required for DNA unwinding and oligomer formation. [PDF]

, 2010
RecQ helicases have attracted considerable interest in recent years due to their role in the suppression of genome instability and human diseases. These atypical helicases exert their function by resolving a number of highly specific DNA structures.
