BLM helicase facilitates telomere replication during leading strand synthesis of telomeres

open access: yesJournal of Cell Biology, 2015
BLM helicase facilitates telomere replication by resolving G-quadruplex structures that can form in the G-rich repeats during leading strand synthesis.

Viral Helicases

open access: yes, 2009
Helicases are motor proteins that use the free energy of NTP hydrolysis to catalyze the unwinding of duplex nucleic acids. Helicases participate in almost all processes involving nucleic acids. Their action is critical for replication, recombination, repair, transcription, translation, splicing, mRNA editing, chromatin remodeling, transport, and ...

Mammalian DNA helicase

open access: yesNucleic Acids Research, 1985
A forked DNA was constructed to serve as a substrate for DNA helicases. It contains features closely resembling a natural replication fork. The DNA was prepared in large amounts and was used to assay displacement activity during isolation from calf thymus DNA polymerases alpha holoenzyme. One form of DNA polymerase alpha holoenzyme is possibly involved

Novel Intragenic Duplication of GATAD2B in a Patient With GAND

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The nucleosome remodeling and deacetylation (NuRD) complex is a major chromatin regulator and plays a critical role in regulating gene transcription, genome integrity, and cell cycle progression. Heterozygous variants in GATAD2B, a core NuRD component, have been reported to cause GATAD2B‐Associated Neurodevelopmental Disorder (GAND), an ...

MCM2–7-dependent cohesin loading during S phase promotes sister-chromatid cohesion

open access: yeseLife, 2018
DNA replication transforms cohesin rings dynamically associated with chromatin into the cohesive form to establish sister-chromatid cohesion. Here, we show that, in human cells, cohesin loading onto chromosomes during early S phase requires the ...

The crystal structure of Zika virus helicase: basis for antiviral drug design

open access: yesProtein & Cell, 2016
The genus of Flavivirus contains important human pathogens, including dengue (DENV), yellow fever (YFV), West Nile (WNV), Japanese encephalitis (JEV), and tick-borne encephalitis (TBEV) viruses, which cause a number of serious human diseases throughout ...

Multiple low dose streptozotocin‐induced diabetes as a model for studying autoimmune diabetes in humans

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Multiple low dose streptozotocin‐induced diabetes is a valuable animal model of diabetes type 1. It should be improved by further research on autoantigens, microbiota and mucosal immune cells from the gut, but also from other organs. Abstract The autoimmune response directed against pancreatic β cells is the most essential pathogenic process in type 1 ...

Disease Mechanisms and Therapeutic Approaches in SMARD1—Insights from Animal Models and Cell Models

open access: yesBiomedicines
Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is a fatal childhood motoneuron disease caused by mutations in the IGHMBP2 gene. It is characterized by muscle weakness, initially affecting the distal extremities due to the degeneration ...
