Cell cycle-dependent phosphorylation of the DNA polymerase epsilon subunit, Dpb2, by the Cdc28 cyclin-dependent protein kinase.

Abstract excerpt

DNA polymerase epsilon (Polepsilon), one of the three major eukaryotic replicative polymerases, is comprised of the essential catalytic subunit, called Pol2 in budding yeast, and three accessory subunits, only one of which, Dpb2, is essential. Polepsilon is recruited to replication origins during late G(1) phase prior to activation of replication. In this work we show that the budding yeast Dpb2 is phosphorylated...
