Our research group studies the S. cerevisiae centromere and kinetochore. The focus of our current work is the gene CSE4, which encodes a novel centromere-specific chromatin protein. |

CSE4 was originally isolated in our lab in 1995 in a genetic screen for yeast mutants defective in chromosome segregation. The original mutant of CSE4 called cse4-1 causes temperature sensitive growth and chromosome missegregation (Stoler, Keith et al 1995). |

|
CSE4 encodes an essential protein containing a domain highly homologous to the histone fold domain (HFD) of the core histone protein, H3. We are using genetic, biochemical and molecular approaches to study Cse4p and thereby further our understanding of how the biomolecular machine at the centromere performs the critical process of chromosome segregation. |
