Protein
DNA polymerase delta small subunit
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
DNA polymerase delta (DNA polymerase III) participates in chromosomal DNA replication. It is required during synthesis of the leading and lagging DNA strands at the replication fork and binds at/or near replication origins and moves along DNA with the replication fork. It has 3'-5' proofreading exonuclease activity that correct errors arising during DNA replication. It is also involved in DNA synthesis during DNA repair.
Similarity
Belongs to the DNA polymerase delta/II small subunit family.
