APE1
APE1

APE1, also known as HAP1 or Ref1, acts as an AP lyase by hydrolyzing the phosphodiester backbone at the 5′ end of an apurinic (AP) site, generating a 1 base gap in the DNA duplex and leaving 3′-hydroxyl and 5′-deoxyribose phosphate termini.

Description:
APE1, also known as HAP1 or Ref1, acts as an AP lyase by hydrolyzing the phosphodiester backbone at the 5'-end of an apurinic (AP) site, generating a 1 base gap in the DNA duplex and leaving 3'-hydroxyl and 5'-deoxyribose phosphate termini. Evidence suggests that APE1 may exhibit weak DNA 3'-diesterase, 3' to 5'-exonuclease and RNase H activities (1-4).

Specific Activity: 2,000,000 U/mg

Applications:

  • Single cell gel electrophoresis (Comet assay)
