Summary
Functional genomics in yeast identifies new DNA damage response genes. High-throughput screening of Saccharomyces cerevisiae mutants accelerates discovery of essential cellular repair pathways.
Area of Science:
- Molecular Biology
- Genetics
- Cell Biology
Background:
- The DNA damage response (DDR) is crucial for maintaining genomic integrity.
- Extensive research in Saccharomyces cerevisiae has elucidated many DDR pathways.
- However, novel genes involved in DDR are continually being discovered.
Purpose of the Study:
- To describe functional genomic approaches for identifying new DDR genes and pathways.
- To leverage the Saccharomyces cerevisiae gene deletion mutant collection for DDR discovery.
Main Methods:
- Utilizing the Saccharomyces cerevisiae gene deletion mutant collection in an ordered array or pooled format.
- Employing high-throughput, automated screening techniques.
- Functional genomic analysis to identify genes involved in DNA repair and stress response.
Main Results:
- Identification of previously unknown genes contributing to the DNA damage response.
- Elucidation of novel components within existing DDR pathways.
- Demonstration of the efficiency of high-throughput functional genomics in DDR research.
Conclusions:
- Functional genomic strategies are powerful tools for discovering novel DDR genes in Saccharomyces cerevisiae.
- Automated, high-throughput screening of mutant collections significantly accelerates the pace of DDR research.
- Continued application of these methods promises further expansion of our understanding of DNA repair mechanisms.

DNA Damage can Stall the Cell Cycle
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Overview of DNA Repair
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Base Excision Repair
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
