Architecture of viral replication factories
Compartmentalization of intracellular membrane is a marked characteristic during the pathogenesis of many viruses, which provides a microenvironment for virus to evade the host RNA interference defense response on one hand, and confines various host factors as well as metabolites in a stable space so that they can act in concert to complete virus replication cycle [1]. Recently, advanced imagin...
متن کاملSetting Up Shop: The Formation and Function of the Viral Factories of Cauliflower mosaic virus
Similar to cells, viruses often compartmentalize specific functions such as genome replication or particle assembly. Viral compartments may contain host organelle membranes or they may be mainly composed of viral proteins. These compartments are often termed: inclusion bodies (IBs), viroplasms or viral factories. The same virus may form more than one type of IB, each with different functions, a...
متن کاملSequence-independent targeting of transmembrane proteins synthesized within vaccinia virus factories to nascent viral membranes.
The primary membrane of vaccinia virus, as well as those of other poxviruses, forms within a discrete cytoplasmic factory region. We recently determined the existence of an operative pathway from the endoplasmic reticulum within the virus factory to nascent viral membranes and demonstrated that a viral protein could be diverted from this pathway to Golgi membranes by the addition of COPII-bindi...
متن کاملThe cellular chaperone hsc70 is specifically recruited to reovirus viral factories independently of its chaperone function.
Mammalian orthoreoviruses replicate and assemble in the cytosol of infected cells. A viral nonstructural protein, μNS, forms large inclusion-like structures called viral factories (VFs) in which assembling viral particles can be identified. Here we examined the localization of the cellular chaperone Hsc70 and found that it colocalizes with VFs in infected cells and also with viral factory-like ...
متن کاملTranscription factories
There is considerable evidence that transcription does not occur homogeneously or diffusely throughout the nucleus, but rather at a number of specialized, discrete sites termed transcription factories. The factories are composed of ~4-30 RNA polymerase molecules, and are associated with many other molecules involved in transcriptional activation and mRNA processing. Some data suggest that the p...
