Adaptation through Translocation
Papers by and, in this issue of Neuron, describe how massive and rapid translocation of specific elements of the phototransduction cascades in different phyla, namely, the G protein (transducin) in vertebrate rods and light-sensitive TRPL channels in the microvillar rhabdomeres of Drosophila, contribute to photoreceptor adaptation.
متن کاملLight Adaptation through Phosphoinositide-Regulated Translocation of Drosophila Visual Arrestin
Photoreceptor cells adapt to bright or continuous light, although the molecular mechanisms underlying this phenomenon are incompletely understood. Here, we report a mechanism of light adaptation in Drosophila, which is regulated by phosphoinositides (PIs). We found that light-dependent translocation of arrestin was defective in mutants that disrupt PI metabolism or trafficking. Arrestin bound t...
متن کاملHeteropolymer translocation through nanopores.
The authors investigate the translocation dynamics of heteropolymers driven through a nanopore using a constant temperature Langevin thermostat. Specifically, they consider heteropolymers consisting of two types of monomers labeled A and B, which are distinguished by the magnitude of the driving force that they experience inside the pore. From a series of studies on polymers with sequences AmBn...
متن کاملPolymer translocation through a nanopore
We investigate the dynamics of polymer translocation through a nanopore under an externally applied field using the 2D fluctuating bond model with single-segment Monte Carlo moves. We concentrate on the influence of the field strength E, length of the chain N, and length of the pore L on forced translocation. As our main result, we find a crossover scaling for the translocation time τ with the ...
متن کاملDNA translocation through graphene nanopores.
We report on DNA translocations through nanopores created in graphene membranes. Devices consist of 1-5 nm thick graphene membranes with electron-beam sculpted nanopores from 5 to 10 nm in diameter. Due to the thin nature of the graphene membranes, we observe larger blocked currents than for traditional solid-state nanopores. However, ionic current noise levels are several orders of magnitude l...
