The Role of Elg1-RFC in Sister Chromatid Cohesion

publication Evidence: high

Author Information

Primary Institution: Lehigh University

Hypothesis

Elg1-RFC participates in sister chromatid cohesion and has distinct functions compared to Ctf18-RFC.

Conclusion

Elg1-RFC plays a significant role in sister chromatid cohesion, distinct from Ctf18-RFC, and its deletion can rescue cohesion defects in certain mutant backgrounds.

Supporting Evidence

  • Elg1 deletion rescues ctf7 mutant cell temperature sensitivity.
  • Over-expression of ELG1 enhances ctf7 mutant cell growth defects.
  • Elg1-RFC does not function redundantly with Ctf18-RFC in cohesion establishment.

Takeaway

Elg1 helps keep sister chromatids together during cell division, and when it's missing, the cells can grow better under certain conditions.

Methodology

The study involved creating various yeast mutant strains and analyzing their growth and cohesion characteristics under different conditions.
