Background

APE1 (apurinic-apyrimidinic endonuclease 1) belongs to DNA repair enzymes AP/ExoA family and plays a key role in cellular response to oxidative stress, DNA repair and redox regulation of transcriptional factors. APE1 functions as apurinic/apyrimidinic (AP) endodeoxyribonuclease in DNA base excision repair (BER) pathway of DNA lesions induced by oxidative stress, alkylating agents, and ionizing radiation. It participates in DNA demethylation for epigenetic regulation of gene expression and delivers endoribonuclease activity for controlling single-stranded RNA metabolism. APE1 acts as a loading factor for POLB onto non-incised AP sites in DNA for stimulating the 5'-terminal dRp-excision activity of POLB and involve in DNA cleavage step of class switch recombination. Together with HNRNPL or XRCC5/XRCC6 dimer, APE1 associates with nCaRE to acting as an activator of transcriptional repression. When acetylated at Lys-6 and Lys-7, APE1 stimulates YBX1-mediated MDR1 promoter activity resulting in drug resistance. Ape1 functions as a redox factor that maintains transcription factors in an active, reduced state and also function in a redox-independent manner as a transcriptional cofactor to control different cellular fates such as apoptosis, proliferation and differentiation. APE1 stimulates DNA binding of several transcription factors known to be involved in tumor progression such as Fos, Jun, NF-kB, PAX, HIF-1, HLF and p53. Increased APE1 expression is associated with many types of cancers including cervical, ovarian, prostate, rhabdomyosarcomas and germ cell tumors, and APE1 mutation has also been associated with amyotrophic lateral sclerosis (ALS).
