Evolutionary degeneration of septins into pseudoGTPases: impacts on a hetero-oligomeric assembly interface

open access: yesFrontiers in Cell and Developmental Biology, 2023
The septin family of eukaryotic proteins comprises distinct classes of sequence-related monomers that associate in a defined order into linear hetero-oligomers, which are capable of polymerizing into cytoskeletal filaments. Like actin and ⍺ and β tubulin,

Barcoded Nucleotides [PDF]

open access: yesAngewandte Chemie International Edition, 2011
DNA as an information storage system is simple and at the same time complex owing to the various different arrangements of the four natural nucleotides.[1] The DNA synthesis by DNA polymerases is intriguing, since these enzymes are able to catalyze the elongation of the primer strand by recognizing the DNA template and selecting the corresponding ...

Dose-Dependent Von Willebrand Factor Inhibition by Aptamer BB-031 Correlates with Thrombolysis in a Microfluidic Model of Arterial Occlusion

open access: yesPharmaceuticals, 2022
Von Willebrand Factor (VWF) plays a critical role in thrombus formation, stabilization, and propagation. Previous studies have demonstrated that targeted inhibition of VWF induces thrombolysis when administered in vivo in animal models of ischemic stroke.

Nucleotide-decorated AuNPs as probes for nucleotide-binding proteins [PDF]

open access: yesScientific Reports, 2021
AbstractGold nanoparticles (AuNPs) decorated with biologically relevant molecules have variety of applications in optical sensing of bioanalytes. Coating AuNPs with small nucleotides produces particles with high stability in water, but functionality-compatible strategies are needed to uncover the full potential of this type of conjugates.

A nuclear orthologue of the dNTP triphosphohydrolase SAMHD1 controls dNTP homeostasis and genomic stability in Trypanosoma brucei

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
Maintenance of dNTPs pools in Trypanosoma brucei is dependent on both biosynthetic and degradation pathways that together ensure correct cellular homeostasis throughout the cell cycle which is essential for the preservation of genomic stability. Both the
