Preprint
Homologous recombination (HR), a principal cellular pathway for double-strand break (DSB) repair, is linked to changes in chromosome movement. Although increased chromosome mobility in response to a DSB has been observed in a variety of species, its precise role in HR remains controversial. Here, we find that end resection, the recruitment of recom...
Chapter
The precise organization of the genome inside the cell nucleus is vital to many cell functions including gene expression, cell division, and DNA repair. Here we describe a method to measure pairing of DNA loci during homologous recombination (HR) at a site-specific double-strand break (DSB) in Saccharomyces cerevisiae. This method utilizes a chromo...

During S phase in Saccharomyces cerevisiae, chromosomal loci become mobile in response to DNA double-strand breaks both at the break site (local mobility) and throughout the nucleus (global mobility). Increased nuclear exploration is regulated by the recombination machinery and the DNA damage checkpoint, and is likely an important aspect of homolog...

The postreplication repair gene, HLTF, is often amplified and overexpressed in cancer. Here we model HLTF dysregulation through the functionally conserved Saccharomyces cerevisiae ortholog, RAD5. Genetic interaction profiling and landscape enrichment analysis of RAD5 overexpression (RAD5OE) reveals requirements for genes involved in recombination,...
Article
During homologous recombination, cells must coordinate repair, DNA damage checkpoint signaling, and movement of chromosomal loci to facilitate homology search. In Saccharomyces cerevisiae, increased movement of damaged loci (local mobility) and undamaged loci (global mobility) precedes homolog pairing in mitotic cells. How cells modulate chromosome...
Article
Standard CRISPR-mediated gene disruption strategies rely on Cas9-induced DNA double-strand breaks (DSBs). Here, we show that CRISPR-dependent base editing efficiently inactivates genes by precisely converting four codons (CAA, CAG, CGA, and TGG) into STOP codons without DSB formation. To facilitate gene inactivation by induction of STOP codons (iST...

The CKS1B gene located on chromosome 1q21 is frequently amplified in breast, lung, and liver cancers. CKS1B codes for a conserved regulatory subunit of cyclin–CDK complexes that function at multiple stages of cell cycle progression. We used a high throughput screening protocol to mimic cancer-related overexpression in a library of Saccharomyces cer...
