1. DNA double-strand break repair in ascomycetes
Sammanfattning : Nonhomologous end joining (NHEJ) and homologous recombination (HR) are two pathways for DNA double strand break (DSB) repair. We found that the NHEJ protein Nej1 interacted physically with the HR protein Srs2, which was dependent on phosphorylation of Nej1 by Dun1. Srs2 recruitment to a DSB partly relied on Nej1 and Dun1.

2. Characterization of Budding Yeast Nonhomologous End-Joining at DNA Double-Strand Breaks and Telomeres
Sammanfattning : The yeast K. lactis efficiently integrates DNA by illegitimate recombination (IR). IR was completely dependent upon nonhomologous end-joining (NHEJ). In contrast to S. LÄS MER
3. Recognition and signaling of DNA double-strand breaks in human cells
Sammanfattning : DNA double-strand breaks (DSBs) are the most toxic type of DNA damage. Fortunately, our cells have highly conserved pathways that detect and repair DSBs. Defects in DSB signaling and DSB repair pathways result in genomic instability that predisposes for cancer development. LÄS MER
4. Radiation response in human cells : DNA damage formation, repair and signaling
Sammanfattning : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. LÄS MER
5. Silencing and DNA double-strand break repair in budding yeast
Sammanfattning : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. LÄS MER
