Positioning of AMPA Receptor-Containing Endosomes Regulates Synapse Architecture

Cell Reports, 2015
Lateral diffusion in the membrane and endosomal trafficking both contribute to the addition and removal of AMPA receptors (AMPARs) at postsynaptic sites.

Actin stress fibre subtypes in mesenchymal-migrating cells [PDF]

Open Biology, 2013
Mesenchymal cell migration is important for embryogenesis and tissue regeneration. In addition, it has been implicated in pathological conditions such as the dissemination of cancer cells.

Visualizing molecules of functional human profilin

eLife, 2022
Profilin-1 (PFN1) is a cytoskeletal protein that regulates the dynamics of actin and microtubule assembly. Thus, PFN1 is essential for the normal division, motility, and morphology of cells.

Chlamydia Hijacks ARF GTPases To Coordinate Microtubule Posttranslational Modifications and Golgi Complex Positioning

mBio, 2017
The intracellular bacterium Chlamydia trachomatis develops in a parasitic compartment called the inclusion. Posttranslationally modified microtubules encase the inclusion, controlling the positioning of Golgi complex fragments around the inclusion.

Actin Cytoskeleton and Golgi Involvement in Barley stripe mosaic virus Movement and Cell Wall Localization of Triple Gene Block Proteins. [PDF]

, 2013
Barley stripe mosaic virus (BSMV) induces massive actin filament thickening at the infection front of infected Nicotiana benthamiana leaves. To determine the mechanisms leading to actin remodeling, fluorescent protein fusions of the BSMV triple gene ...

A distributed residue network permits conformational binding specificity in a conserved family of actin remodelers

eLife, 2021
Metazoan proteomes contain many paralogous proteins that have evolved distinct functions. The Ena/VASP family of actin regulators consists of three members that share an EVH1 interaction domain with a 100 % conserved binding site.

Mathematical modelling and numerical simulations of actin dynamics in the eukaryotic cell [PDF]

, 2012
The aim of this article is to study cell deformation and cell movement by considering both the mechanical and biochemical properties of the cortical network of actin filaments and its concentration.

Phosphoprofile reorganization of the actin binding protein Drebrin during long term depression

Frontiers in Molecular Neuroscience
Drebrin (DBN), an actin-binding protein critical for the structural integrity and function of dendritic spines, is highly phosphorylated at steady state in neurons.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

A new family of bacterial actin-like proteins regulates cell morphology in a filamentous cyanobacterium

mSphere
Actin proteins are common to all domains of life and exhibit ATP-dependent polymerization to form filaments. In bacteria, four families of bacterial actin-like proteins (BALPs) have been identified and characterized.
