Mammalian Homologs of Yeast Checkpoint Genes

Abstract

We hypothesize that components of DNA-related checkpoint pathways in addition to members of the ATM protein/lipid kinase family are conserved in all eukaryotes. This is based on functional similarities in the pathways and the conservation between evolutionarily disparate budding and fission yeasts. Our goal is to identify additional regulators of mammalian DNA checkpoints, virtue of structural and functional homology with known checkpoint genes in budding yeast. We will use both structural and functional screens to identify human homologs of yeast damage checkpoint proteins Rad53 and Rad9. Once identified, such components will be ordered into pathways for mammalian checkpoint function, with emphasis on p53 regulation, cell cycle regulation and complementation of ATM defects.
