AbstractProtein allostery, a chemical‐to‐mechanical effect that can precisely regulate protein structure, exists in many proteins. Herein, we demonstrate that protein allostery can be used to drive self‐assembly for the construction of tunable protein architectures. Calmodulin (CaM) was chosen as a model allosteric protein. Ca2+‐mediated contraction of

Cortical microfilament proteins and the dynamics of the plasma membrane.
Acta histochemica. Supplementband, 1992The microfilament system is thought to provide motor elements needed for plasma membrane dynamics. This article focuses on two protein components that may play key roles in this process: (1) Profilin, a G-actin binding protein which is considered as the source of actin subunits necessary for rapid changes in the amount of actin filaments.

ABSTRACT Fluorescently labelled contractile proteins (alpha-actinin and filamin) were used to study the dynamic nature of three types of microfilament bundles: myofibrils, stress fibres and polygonal networks. Cultured muscle and non-muscle cells that were microinjected with fluorescent alphaactinin rapidly incorporated the labelled ...

Staurosporine induces dissolution of microfilament bundles by a protein kinase C-independent pathway
Experimental Cell Research, 1990The protein kinase C (PKC) inhibitor staurosporine was found to dramatically alter the actin microfilament cytoskeleton of a variety of cultured cells, including PTK2 epithelial cells, Swiss 3T3 fibroblasts, and human foreskin fibroblasts. For example, PTK2 cells exposed to 20 nM staurosporine exhibited a progressive thinning and loss of cytoplasmic ...

AbstractSperm from the decapod crustacean Rhynchocinetes typus undergo dramatic shape changes as they pass from the vas deferens to seawater and interact with the oocyte envelopes. Using FITC‐phalloidin and antitubulin antibodies, we were able to localize microfilaments and a tubulin‐like protein in R. typus spermatozoon. Microfilaments and the tubulin‐

A specific polyclonal antibody has been raised against a basic cytoplasmic protein (p27) which is induced by serum in growth-arrested NIH 3T3 cells but is constitutively expressed in nonestablished fibroblasts. Immunoblotting analysis and [35S]methionine labeling show that p27 is absent in tissues and established cell lines of different types. However,

The proline-rich focal adhesion and microfilament protein VASP is a ligand for profilins.
The EMBO Journal, 1995Profilins are small proteins that form complexes with G-actin and phosphoinositides and are therefore considered to link the microfilament system to signal transduction pathways. In addition, they bind to poly-L-proline, but the biological significance of this interaction is not yet known.
