Genetic information is packaged in the highly dynamic nucleoprotein structure called chromatin. Many biological processes are regulated via post-translational modifications of key proteins. Acetylation of lysine residues at the N-terminal histone tails is one of the most studied covalent modifications influencing gene regulation in eukaryotic cells. This review focuses on the role of enzymes in...

BACKGROUND Recent studies clearly suggest that regulatory T cells play a critical role in the control of the immunoinflammatory response in atherosclerosis and substantially limit lesion development. Measles virus infection or vaccination is associated with immune depression, in part through the induction of an antiinflammatory response by measles virus nucleoprotein. We hypothesized that the a...

We constructed a cDNA clone of canine distemper virus (CDV) encoding an entire nucleoprotein (NP) gene, by means of the reverse transcription-polymerase chain reaction (RT-PCR). The cloned NP gene was inserted into the eucaryotic expression vector, pRVSV. After transfection of the plasmid into Vero cells, we examined the expression of CDV-specific NP antigen by means of indirect immunofluoresce...

The nucleotide sequence of the nucleoprotein gene of influenza A/NT/60/68 was established after using improved cloning methods to obtain full length cDNA clones in pBr322. The gene is 1565 residues long and codes for a basic protein of 498 amino acids. There are only 30 amino acid differences between it and the homologous sequence in A/PR/8/35, all occurring as point mutations. Assuming a commo...

Bionanotechnology is an emerging field with great promise in molecular science. The field is so new that it has yet to be formally defined. However, it can be characterized as a primitive technology that takes advantage of the properties of highly evolved natural products like nucleic acids and proteins by attempting to harness them to achieve new and useful functionalities on the nanoscale. It...
