Abstract
Apurinic/apyrimidinic endonuclease 1 (APE1) is the predominant mammalian enzyme in DNA base excision repair pathway that cleaves the DNA backbone immediately 5′ to abasic sites. In addition to its abasic endonuclease activity, APE1 has 3′ phosphatase and 3′–5′ exonuclease activities against DNA. We recently identified APE1 as an endoribonuclease that preferentially cleaves at UA, UG, and CA sites in single-stranded regions of RNAs and can...
