The Role Of The Ku70 Vwa Domain In The Response To Dna Double Strand Breaks, Victoria L. Fell
Electronic Thesis and Dissertation Repository
Ku is an abundant, highly conserved DNA binding protein found in both prokaryotes and eukaryotes that plays essential roles in the maintenance of genome integrity. In eukaryotes, Ku is a heterodimer comprised of two subunits, Ku70 and Ku80, and is best characterized for its central role as the initial DNA end binding factor in the “classical” non-homologous end joining (C-NHEJ) pathway, the main DNA double-strand break (DSB) repair pathway in mammals. At the break, Ku directly and indirectly interacts with several C-NHEJ factors and processing enzymes, serving as the scaffold for the entire DNA repair complex. In this work we …
