Phage FC31 integrase has potential as a means of inserting therapeutic genes into specific sites in the human genome. However, the possible interactions between FC31 integrase and cellular proteins have never been investigated. Using pLexA-FC31 integrase as bait, we screened a pB42AD-human fetal brain cDNA library for potential interacting cellular proteins. Among 61 positives isolated from 10 ...
The effects of 3'-azido-3'-deoxythymidine (AZT) and three of its intracellular metabolites, azido- thymidine mono-, di-, and triphosphates, on the human immunodeficiency virus type 1 integrase have been determined. AZT mono-, di-, and triphosphate have an IC50 for integration between 110 and 150 microM, whereas AZT does not inhibit the integrase. The inhibition by AZT monophosphate can be parti...
Integration of the HIV-1 cDNA into the human genome is catalyzed by the viral integrase (IN) protein. Several studies have shown the importance of cellular cofactors that interact with integrase and affect viral integration and infectivity. In this study, we produced a stable complex between HIV-1 integrase, viral U5 DNA, the cellular cofactor LEDGF/p75 and the integrase binding domain of INI1 ...
Few nonviral techniques exist for efficient and stable eukaryotic gene transfer and fewer still are broadly useful in both cell culture and whole-organism applications. C31 integrase, a site-specific bacteriophage recombinase, is able to catalyze chromosomal transgene insertion under a diverse range of experimental and therapeutic conditions. The enzyme recognizes and catalyzes unidirectional r...
Background HIV integrase (IN) plays important roles at several steps, including viral DNA nuclear import, targeting viral DNA to host chromatin and integration. Identification of novel inhibitors of HIV Integrase has emerged as promising antiviral agents for the treatment of HIV/AIDS. Present work is to investigation of anti-HIV activity and HIV integrase inhibitory activity of various extracts...
HIV integrase is a 32 kDa protein produced from the C-terminal portion of the Pol gene product, and is an attractive target for new anti-HIV drugs. Integrase is an enzyme produced by a retrovirus (such as HIV) that enables its genetic material to be integrated into the DNA of the infected cell. Raltegravir and Elvitegravir are two important drugs against integrase.
CITED2 is a transcriptional co-activator with 3 conserved domains shared with other CITED family members and a unique Serine-Glycine Rich Junction (SRJ) that is highly conserved in placental mammals. Loss of Cited2 in mice results in cardiac and aortic arch malformations, adrenal agenesis, neural tube and placental defects, and partially penetrant defects in left-right patterning. By screening ...
background: the aim of this study was to produce a stable cho cell line expressing tenecteplase. materials and methods: in the first step, the tenecteplase coding sequence was cloned in a pdb2 vector containing attb recognition sites for the phage φc31 integrase. then, using lipofection, the cho cells were co-transfected with constructed recombinant plasmid encoding tenecteplase and attb recogn...
Due to their ability to integrate into the host cell's genome, retroviruses represent an optimal basis for the creation of gene therapy vectors. The integration reaction is carried out by a viral enzyme integrase: thus, a detailed research of this enzyme is required. In this work, the catalytic properties of human foamy virus integrase were studied. This virus belongs to the Retroviridae family...
