Homologous Recombination as a Replication Fork Escort: Fork-Protection and Recovery
Homologous recombination is a universal mechanism that allows DNA repair and ensures the efficiency of DNA replication. The substrate initiating the process of homologous recombination is a single-stranded DNA that promotes a strand exchange reaction resulting in a genetic exchange that promotes genetic diversity and DNA repair. The molecular mechanisms by which homologous recombination repairs...
متن کاملNek1 Regulates Rad54 to Orchestrate Homologous Recombination and Replication Fork Stability.
Never-in-mitosis A-related kinase 1 (Nek1) has established roles in apoptosis and cell cycle regulation. We show that human Nek1 regulates homologous recombination (HR) by phosphorylating Rad54 at Ser572 in late G2 phase. Nek1 deficiency as well as expression of unphosphorylatable Rad54 (Rad54-S572A) cause unresolved Rad51 foci and confer a defect in HR. Phospho-mimic Rad54 (Rad54-S572E), in co...
متن کاملDesigning E1 Deleted Adenoviral Vector by Homologous Recombination
Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...
متن کاملHomologous recombination
DNA damage, in the form of DNA double-strand breaks, poses a considerable threat to genomic integrity and cell survival. If left unrepaired, a single double-strand break is sufficient to cause cell death and, if repaired inappropriately, a double-strand break may give rise to a potentially oncogenic translocation. Double-strand breaks in genomic DNA may arise accidentally in a number of ways, i...
متن کاملRecombination: Homologous recombination branches out
Homologous recombination can be divided into three key steps: strand exchange, branch migration and resolution. The identification of a protein complex that catalyses branch migration and Holliday junction resolution argues that the mechanism of homologous recombination is conserved from bacteria to man.
