DNA transposition: Assembly of a jumping gene machine
Mobile DNA sequences can ‘jump’ or transpose from one location to another in a host genome, and can have profound biological effects on an organism. Many of these elements, found in diverse organisms from bacteria to humans and including retroviruses such as HIV, transpose using a similar mechanism. Our understanding of this process comes largely from extensive studies on bacteriophage Mu, for ...
متن کاملStudies on a "jumping gene machine": higher-order nucleoprotein complexes in Mu DNA transposition.
Studies in my lab have focused on DNA transposition in the bacterial virus, Mu. In vitro studies have shown that Mu DNA transposition is a three-step process involving DNA breakage, strand transfer and DNA replication. In the first step, a nick is introduced at each end of the transposon. The liberated 3'-OH groups subsequently attack a target DNA molecule resulting in strand transfer. The tran...
متن کاملConstruction of a recombinant bacmid DNA containing influenza A virus hemagglutinin gene using a site-specific transposition mechanism
Introduction: In recent years, influenza viruses have caused moderate to severe infections all around the world while so far there is no influenza vaccine that can protect people with only one dose of injection. In this regard, producing a universal vaccine based on virus-like-particles (VLP) could be an ideal approach. Methods: In this study, the full-length ORF of influenza hemagglutini...

متن کاملOGG1 DNA Repair Gene Polymorphism As a Biomarker of Oxidative and Genotoxic DNA Damage
Background: Single nucleotide polymorphisms in 8-oxoguanine DNA glycosylase-1 (OGG1) gene modulates DNA repair capacity and functions as one of the first lines of protective mechanisms against 8-hydroxy-2’-deoxyguanosine (8-OHdG) mutagenicity. OGG1-Cys326 gene polymorphism may decrease DNA repair function, causing oxidative stress due to higher oxidative DNA damage. The main purpose of this stu...
