Systematic name YBR278W
Gene name DPB3
Aliases
Feature type ORF, Verified
Coordinates Chr II:760294..760899
Primary SGDID S000000482


Description of YBR278W: Third-largest subunit of DNA polymerase II (DNA polymerase epsilon); required to maintain fidelity of chromosomal replication and also for inheritance of telomeric silencing; stabilizes the interaction of Pol epsilon with primer-template DNA, positively affecting the processivity of the polymerase and exonuclease activities of Pol epsilon; mRNA abundance peaks at the G1/S boundary of the cell cycle[1][2][3][4]
