Ultrastructural Study of Rotavirus Replication and Localization of the Intermediate Capsid Protein VP6
Rotavirus, a triple-layered non-enveloped member of the Reoviridae family, obtained a transient membrane envelope when newly synthesized subviral particles bud into the endoplasmic reticulum (ER). As rotavirus particles mature, they lose their transient membrane and obtain outer layer. It is mostly believed that only double layered particles bud into the ER. The present study describes that the...
متن کاملUV-induced hyperphosphorylation of replication protein a depends on DNA replication and expression of ATM protein.
Exposure to DNA-damaging agents triggers signal transduction pathways that are thought to play a role in maintenance of genomic stability. A key protein in the cellular processes of nucleotide excision repair, DNA recombination, and DNA double-strand break repair is the single-stranded DNA binding protein, RPA. We showed previously that the p34 subunit of RPA becomes hyperphosphorylated as a de...
متن کاملProtein interactomes of protein phosphatase 2A B55 regulatory subunits reveal B55-mediated regulation of replication protein A under replication stress
The specific function of PP2A, a major serine/threonine phosphatase, is mediated by regulatory targeting subunits, such as members of the B55 family. Although implicated in cell division and other pathways, the specific substrates and functions of B55 targeting subunits are largely undefined. In this study we identified over 100 binding proteins of B55α and B55β in Xenopus egg extracts that are...
متن کاملrpb۵-mediating protein suppresses hepatitis b virus (hbv) transcription and replication by counteracting the transcriptional activation of hepatitis b virus x protein in hbv replication mouse model
conclusions our study demonstrated that a low dose of rmp could inhibit hbv transcription and replication, which is dependent on the appearance of hbx in vivo. results rpb5-mediating protein could inhibit hbv transcription and replication in groups transfected with the 1.2 wt and hbx. the inhibitory effect disappeared in the 1.2x (-) groups, yet it reappeared in the groups co-transfected with 1...
متن کاملPurification and characterization of replication protein A, a cellular protein required for in vitro replication of simian virus 40 DNA.
The replication of simian virus 40 (SV40) DNA is largely dependent upon cellular replication proteins. To define these proteins we have made use of a cell-free system that is capable of replicating plasmid DNA molecules containing the SV40 origin of replication. Systematic fractionation-reconstitution experiments indicate that there are a minimum of six cellular proteins that are required for e...
