Regulation of homologous recombination in eukaryotes.
Homologous recombination (HR) is required for accurate chromosome segregation during the first meiotic division and constitutes a key repair and tolerance pathway for complex DNA damage, including DNA double-strand breaks, interstrand crosslinks, and DNA gaps. In addition, recombination and replication are inextricably linked, as recombination recovers stalled and broken replication forks, enab...
متن کاملHomologous recombination and its regulation
Homologous recombination (HR) is critical both for repairing DNA lesions in mitosis and for chromosomal pairing and exchange during meiosis. However, some forms of HR can also lead to undesirable DNA rearrangements. Multiple regulatory mechanisms have evolved to ensure that HR takes place at the right time, place and manner. Several of these impinge on the control of Rad51 nucleofilaments that ...
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 کاملRegulation of DNA strand exchange in homologous recombination.
Homologous recombination, the exchange of DNA strands between homologous DNA molecules, is involved in repair of many structural diverse DNA lesions. This versatility stems from multiple ways in which homologous DNA strands can be rearranged. At the core of homologous recombination are recombinase proteins such as RecA and RAD51 that mediate homology recognition and DNA strand exchange through ...
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...
