Research Interests
Genome stability in yeast.
(I) Genome Integrity: Cells are constantly exposed to various genotoxins that can cause DNA replication stress and affect genome integrity. However, cells employ various means to respond to insults by the genotoxins. Checkpoints, DNA replication machinery and DNA repair systems maintain genome integrity. Data from budding yeast show that various other pathways also respond to genotoxin exposure. We are studying cross-talks between the DNA integrity pathway proteins and proteins of other pathways such as sphingolipid pathway, actin and actin regulators in the maintenance of genome integrity and cell survival.
(II) Recombination and aging: Programmed replication arrest in yeast ribosomal DNA has been shown to induce recombination that plays a key role yeast lifespan. Our interest is to dissect the recombination pathways that controls yeast lifespan.
