DNA polymerase lambda also known as pol λ or DNA pol λ is a DNA polymerase protein involved in DNA repair and replication processes. It has a molecular weight of approximately 65 kDa. DNA polymerase lambda is expressed in various tissues but shows a high concentration in testis and thymus indicating its role in germ cells and immune response. The enzyme exhibits both DNA polymerase and terminal transferase activities facilitating DNA synthesis across gaps and lesions.
Biological function summary
DNA polymerase lambda acts as a gap-filling enzyme during DNA repair processes especially in base excision repair and non-homologous end joining. This polymerase does not typically function within a larger complex but requires accessory factors to perform its repair functions. It maintains genomic stability by providing an accurate extension of DNA strands during repair ensuring the correct rejoining of DNA. Furthermore it also exhibits a lyase activity that can remove 5'-deoxyribose phosphate residues.
Pathways
DNA polymerase lambda is actively involved in the base excision repair and non-homologous end joining pathways. These pathways are important for fixing DNA single-strand breaks and double-strand breaks respectively. Pol λ works alongside proteins like XRCC1 in the short-patch base excision repair pathway and interacts with KU70/80 in non-homologous end joining reinforcing its multifaceted role in maintaining DNA integrity under varying genotoxic stress conditions.
DNA polymerase lambda is linked to conditions such as cancer and immunodeficiencies where its dysfunction can lead to genomic instability. The loss or aberrant function of DNA pol λ may result in ineffective DNA repair contributing to cancer development due to accumulated DNA damage. It can also interact with tumor suppressor p53 highlighting its involvement in pathways that prevent oncogenesis. Additionally impairments in its function can contribute to immunodeficiency disorders as proper DNA repair is essential for the development and function of the immune system.
