AP endonuclease (APE/Ref1 or Apurinic/apyrimidinic endonuclease) is a crucial enzyme in the DNA base excision repair (BER) pathway. It recognizes baseless sites in the DNA following spontaneous base loss or removal of a damaged base by different DNA glycosylases. This enzyme is the major AP endonuclease in mammalian cells. The human enzyme shows a high degree of homology with other mammalian AP endonucleases (bovine, mouse, rat, and hamster). APE/Ref1 is a multifunctional enzyme. Its N-terminal region includes a nuclear localization sequence and a redox activity zone, while its AP endonuclease activity resides in the C-terminal region. Redox-factor 1 (Ref1) refers to the reduction/oxidation function of the enzyme.
Monoclonal Anti-AP Endonuclease recognizes human, canine, rat, and mouse AP endonuclease (approx. 37kDa).
The AP endonuclease is a DNA damage repair gene involved in base excision repair.

生化／生理作用
AP endonuclease (APE/Ref1 or Apurinic/apyrimidinic endonuclease) has a 3′-repair diesterase or phosphatase activity. The major DNA repair activity of the enzyme is nicking the DNA phosphodiester backbone 5′ to the AP site leaving a 3′-hydroxyl group and a 5′-deoxyribose phosphate. APE/Ref1 stimulates the DNA binding activity of many transcription factors (Fos, Jun, NF?B, PAX, HIF1, p53 and CREB), which are involved in cancer promotion and progression. The protein was found at elevated levels in several tumors (ovarian, prostate, cervical and germ cells). Redox-factor 1 (Ref1) maintains transcription factors in their active reduced states.

Transgenesis enables the elucidation of gene function; however, constant transgene expression is not always desired. The tetracycline responsive system was devised to turn on and off transgene expression at will. It has two components: a doxycycline (dox)-controlled transactivator (TA) and
We have previously shown that mitochondria-targeted vitamin E (Mito-Vit-E), a mtROS specific antioxidant, improves cardiac performance and attenuates inflammation in a pneumonia-related sepsis model. In this study, we applied the same approaches to decipher the signaling pathway(s) of mtROS-dependent cardiac
DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.
