The DNA polymerase domain of pol(epsilon) is required for rapid, efficient, and highly accurate chromosomal DNA replication, telomere length maintenance, and normal cell senescence in Saccharomyces cerevisiae.

Abstract excerpt

Saccharomyces cerevisiae POL2 encodes the catalytic subunit of DNA polymerase epsilon. This study investigates the cellular functions performed by the polymerase domain of Pol2p and its role in DNA metabolism. The pol2-16 mutation has a deletion in the catalytic domain of DNA polymerase epsilon that eliminates its polymerase and exonuclease activities. It is a viable mutant, which displays temperature sensitivity...
