This study introduces Multi-perturbation Shapley Value Analysis (MSA) to quantify gene importance in yeast DNA repair. The novel method reveals functional gene interactions and predicts new protein complexes in the Rad6 pathway.

Area of Science:

  • Systems Biology
  • Molecular Biology
  • Genetics

Background:

  • Defining functional causal contributions in biological systems is challenging.
  • Multi-knockout experiments are emerging as crucial for systems analysis.

Purpose of the Study:

  • To apply the novel Multi-perturbation Shapley Value Analysis (MSA) method to gene knockout data.
  • To rigorously analyze the Rad6 DNA repair pathway in yeast (S. cerevisiae).

Main Methods:

  • Application of Multi-perturbation Shapley Value Analysis (MSA) to gene knockout data.
  • Quantification of individual gene contributions and functional interactions within the Rad6 pathway.

Main Results:

  • Identified the importance of specific genes in the yeast Rad6 DNA repair pathway.
