Cse4p is an essential histone H3 variant in Saccharomyces cerevisiae that defines centromere identity and is required for proper segregation of chromosomes. In this study, we investigated phenotypic consequences of Cse4p mislocalization and increased dosage of histone H3 and Cse4p, and established a direct link between histone stoichiometry, mislocalization(More)
It has been more than two decades since the original chromosome transmission fidelity (Ctf) screen of Saccharomyces cerevisiae was published. Since that time the spectrum of mutations known to cause Ctf and, more generally, chromosome instability (CIN) has expanded dramatically as a result of systematic screens across yeast mutant arrays. Here we describe a(More)
How subunit dosage contributes to the assembly and function of multimeric complexes is an important question with implications in understanding biochemical, evolutionary, and disease mechanisms. Toward identifying pathways that are susceptible to decreased gene dosage, we performed a genome-wide screen for haploinsufficient (HI) genes that guard against(More)
