The microfilament system is thought to be a crucial cytoskeletal component regulating development and mature function of neurons. The intracellular distribution of the microfilament isoform components, actin and tropomyosin (Tm), in neurons primarily in vivo, has been investigated at both the mRNA and the protein level using isoform specific riboprobes

During the onset of transformation, Rous sarcoma virus-infected cells undergo characteristic morphological changes that reflect the biochemical events induced by the viral src gene. Temperature downshift experiments using chick embryo cells infected with transformation-defective temperature-sensitive viral mutants have shown two major morphological ...

The effects of protein kinase C (PKC) in the control of osteoclast activity are still unknown. We investigated the role of the enzyme in the control of microfilament organization, podosome assembly, bone resorption, and extracellular Ca2+ sensing in chicken and rabbit osteoclasts treated with agents known to affect PKC activity. Cells were treated for

Velocity sedimentation by sucrose density gradient centrifugation has been used to characterize ascites microvillar microfilament cores and to identify microfilament-associated proteins. Fluoride, calcium, phalloidin and chemical cross-linking treatments of microvilli during Triton X-100 extractions increase the sedimentation rate of the microfilament ...

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.

We have investigated IgG antibodies to microfilament-associated proteins in sera from 29 normal controls and from 172 patients with autoimmune diseases such as rheumatoid arthritis (n = 45), systemic lupus erythematosus (n = 43), polymyositis/dermatomyositis (n = 36), systemic sclerosis (n = 35), and autoimmune chronic active hepatitis (CAH, n = 13 ...

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

The mechanism of Fos-induced transformation is still poorly understood. In the present study, we have asked whether genes whose products play a role in determining cell morphology might become deregulated in the course of Fos-induced transformation. A clear up-regulation in Fos-transformed rat fibroblasts was seen with ezrin, as well as tropomyosin (TM)

Microtubules and microfilaments are highly conserved cytoskeletal polymers hypothesized to play essential biomechanical roles in the unusual gliding motility of Apicomplexan zoites and in their invasion of, and development within, host epithelial cells. We have identified and isolated Cryptosporidium parvum genes encoding the microtubule proteins alpha-
