Previously, we have shown that melanosomes of Xenopus laevis melanophores are transported along both microtubules and actin filaments in a coordinated manner, and that myosin V is bound to purified melanosomes (Rogers, S., and V.I. Gelfand. 1998. Curr. Biol. 8:161-164). In the present study, we have demonstrated that myosin V is the actin-based motor(More)
Indirect immunofluorescent microscopy was used to study the distribution of elongation factor 2 (eEF-2) in fixed human skin diploid and mouse embryo fibroblasts. It was found earlier that some of the eEF-2, ribosomes and initiation factor 2 (eIF-2) are co-localized with a part of the actin microfilament bundles in these cells (Gavrilova et al., 1987;(More)
Interactions with vimentin intermediate filaments (VimIFs) affect the motility, distribution, and anchorage of mitochondria. In cells lacking VimIFs or in which VimIF organization is disrupted, the motility of mitochondria is increased relative to control cells that express normal VimIF networks. Expression of wild-type VimIF in vimentin-null cells causes(More)
Stimulation of Na(+)/K(+)-ATPase activity in alveolar epithelial cells by cAMP involves its recruitment from intracellular compartments to the plasma membrane. Here, we studied the role of the actin molecular motor myosin-V in this process. We provide evidence that, in alveolar epithelial cells, cAMP promotes Na(+)/K(+)-ATPase recruitment to the plasma(More)
This paper reviews security problems in computer networks with dynamically reconfigurable topology (e.g. mesh, MANET, computing grid, virtualized network clusters, fog computing network). The dynamically organized networks might be subjected to some specific computer attacks, which are analyzed within this paper. Different methods of security improvement(More)
In this study we show that binding of mitochondria to vimentin intermediate filaments (VIF) is regulated by GTPase Rac1. The activation of Rac1 leads to a redoubling of mitochondrial motility in murine fibroblasts. Using double-mutants Rac1(G12V, F37L) and Rac1(G12V, Y40H) that are capable to activate different effectors of Rac1, we show that mitochondrial(More)
Internet of Things (IoT) is one of the most rapidly developing information technology concept in the world. Ensuring the safety of IoT is a complex task which has not been completely solved so far. A prospective approach for security providing in IoT is development of a security information and event management (SIEM) system for IoT. For realizing this(More)
