EFhd2/Swiprosin-1 is a cytoskeletal Ca2+-binding protein implicated in Ca2+-dependent cell spreading and migration in epithelial cells. EFhd2 domain architecture includes an N-terminal disordered region, a PxxP motif, two EF-hands, a ligand mimic helix and a C-terminal coiled-coil domain. We reported previously that EFhd2 displays F-actin bundling activity in the presence of Ca2+ and this activ...
Proteins that cross-link actin filaments can either form bundles of parallel filaments or isotropic networks of individual filaments. We have found that mixtures of actin filaments with alpha-actinin purified from either Acanthamoeba castellanii or chicken smooth muscle can form bundles or isotropic networks depending on their concentration. Low concentrations of alpha-actinin and actin filamen...
Revenue maximization in multi-item settings is notoriously elusive. This paper studies a class of two-item auctions which we call a mixed-bundling auction with reserve prices (MBARP). It calls VCG on an enlarged set of agents by adding the seller—who has reserve valuations for each bundle of items—and a fake agent who receives nothing nor has valuations for any item or bundle, but has a valuati...
High expression of the actin bundling protein Fascin increases the malignancy of tumor cells. Here we show that fascin expression is up-regulated in more malignant sub-cell lines of MDA-MB-231 cells as compared to parental cells. Since also parental MDA-MB-231 cells exhibit high fascin levels, increased fascin expression was termed as "hyperexpression". To examine the effect of fascin hyperexpr...
Elongation factor 1 alpha (EF1 alpha) is an abundant protein that binds aminoacyl-tRNA and ribosomes in a GTP-dependent manner. EF1 alpha also interacts with the cytoskeleton by binding and bundling actin filaments and microtubules. In this report, the effect of purified EF1 alpha on actin polymerization and depolymerization is examined. At molar ratios present in the cytosol, EF1 alpha signifi...
The intestinal epithelial cell brush border exhibits distinct localizations of the actin-binding protein components of its cytoskeleton. The protein interactions that dictate this subcellular organization are as yet unknown. We report here that tropomyosin, which is found in the rootlet but not in the microvillus core, can bind to and saturate the actin of isolated cores, and can cause the diss...
The food varieties which complete what seems like a forever cycle from development to bundling through nanotechnology are known as Nano food, for instance, we devouring some braced that has nanoparticles iron, zinc, omega 3, and coenzymes. Numerous sources normally having safe nanoparticles, get processed in the body at nanoscale. have high dietary benefits less bad cholesterol. They cutting-ed...
