Four protein-based genetic determinants or prions-[SWI(+)], [MCA], [OCT(+)], and [MOT3(+)]-are recent additions to the list of well-known Saccharomyces cerevisiae prions, [PSI(+)], [URE3], and [PIN(+)]. A rapid expansion of this list may indicate that many yeast proteins can convert into heritable prion forms and underscores a problem of prion input into(More)
Yeast DNA polymerase ε (Pol ε) is a highly accurate and processive enzyme that participates in nuclear DNA replication of the leading strand template. In addition to a large subunit (Pol2) harboring the polymerase and proofreading exonuclease active sites, Pol ε also has one essential subunit (Dpb2) and two smaller, non-essential subunits (Dpb3 and Dpb4)(More)
DNA polymerase ε (Pol ε) participates in the synthesis of the leading strand during DNA replication in Saccharomyces cerevisiae. Pol ε comprises four subunits: the catalytic subunit, Pol2, and three accessory subunits, Dpb2, Dpb3 and Dpb4. DPB2 is an essential gene with unclear function. A genetic screen was performed in S. cerevisiae to isolate lethal(More)
