Electrostatics at the nanoscale.
Electrostatic forces are amongst the most versatile interactions to mediate the assembly of nanostructured materials. Depending on experimental conditions, these forces can be long- or short-ranged, can be either attractive or repulsive, and their directionality can be controlled by the shapes of the charged nano-objects. This Review is intended to serve as a primer for experimentalists curious...
متن کاملQuantitative nanoscale electrostatics of viruses.
Electrostatics is one of the fundamental driving forces of the interaction between biomolecules in solution. In particular, the recognition events between viruses and host cells are dominated by both specific and non-specific interactions and the electric charge of viral particles determines the electrostatic force component of the latter. Here we probe the charge of individual viruses in liqui...
متن کاملHURP Regulates Chromosome Congression by Modulating Kinesin Kif18A Function
Chromosome biorientation and congression during mitosis require precise control of microtubule dynamics [1-4]. The dynamics of kinetochore microtubules (K-MTs) are regulated by a variety of microtubule-associated proteins (MAPs) [4-9]. Recently, a MAP known as HURP (hepatoma upregulated protein) was identified [10-12]. During mitosis, Ran-guanosine 5'-triphosphate (RanGTP) releases HURP from th...
متن کاملMechanisms of Chromosome Congression during Mitosis
Chromosome congression during prometaphase culminates with the establishment of a metaphase plate, a hallmark of mitosis in metazoans. Classical views resulting from more than 100 years of research on this topic have attempted to explain chromosome congression based on the balance between opposing pulling and/or pushing forces that reach an equilibrium near the spindle equator. However, in mamm...
متن کاملBuilding an integrated model of chromosome congression.
A universal feature of mitosis is that all chromosomes become aligned at the spindle equator--the halfway point between the two spindle poles--prior to anaphase onset. This migratory event is called congression, and is powered by centromere-bound protein machines called kinetochores. This Commentary aims to document recent advances concerning the two kinetochore-based force-generating mechanism...
