1. 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
2. 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
3. Genomic rearrangements at the cause of three genetic disorders in man
Sammanfattning : Genomic rearrangements are a common cause of genetic disorders in man. This thesis describes the analysis of genomic rearrangements observed in patients with the Hunter syndrome (MPS II), incontinentia pigmenti (IP) and the Blepharophimosis, ptosis and epicanthus inversus syndrome (BPES). MPS II is an X-linked recessive lysosomal storage disorder. LÄS MER
4. Role of DNA repair in class switch recombination and somatic hypermutation
Sammanfattning : Class switch recombination (CSR) and somatic hypermutation (SHM), occurring in the germinal center, are two important processes for B cell development. Both are initiated by activation-induced cytidine deaminase (AID), through deamination of the C residues in the variable and switch regions of the immunoglobulin locus, resulting in either in single stranded or double stranded DNA breaks.

5. 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.
