Protein: DNA polymerase epsilon catalytic subunit A (EC 2.7.7.7) (3'-5' exodeoxyribonuclease) (EC 3.1.11.-) (DNA polymerase II subunit A) (P21951)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Catalytic component of the DNA polymerase epsilon complex which participates in chromosomal DNA replication. Required during synthesis of the leading DNA strands at the replication fork, binds at/or near replication origins and moves along DNA with the replication fork. Has 3'-5' proofreading exonuclease activity that corrects errors arising during DNA replication.
Subcellular location: Nucleus.
