DNA polymerase epsilon catalytic subunit A, also known as 3'-5' exodeoxyribonuclease, plays a pivotal role in chromosomal DNA replication. It is a key component of the DNA polymerase epsilon complex, essential for the synthesis of leading DNA strands at the replication fork. This protein not only binds at or near replication origins but also travels with the replication fork, ensuring high fidelity of DNA replication through its 3'-5' proofreading exonuclease activity. Additionally, it participates in DNA repair processes, including DNA synthesis during DNA repair and excision repair synthesis following UV irradiation.

Therapeutic significance:

Given its crucial role in DNA replication and repair, DNA polymerase epsilon catalytic subunit A is directly linked to diseases such as Colorectal cancer 12, characterized by a predisposition to colorectal adenomas and carcinomas. Understanding the role of DNA polymerase epsilon catalytic subunit A could open doors to potential therapeutic strategies, especially in targeting genetic alterations associated with cancer progression.
