Anti-NTH1 (E. coli Endonuclease III Homologue)

Oxygen radicals damage chromosonal DNA causing cell death and inducing mutations. Although a major focus of oxidatively damaged DNA has centered on the repair of 8-oxo-G, a number of other damaged DNA sites are created by free-radical attack on DNA. The human NTH1 repair protein is one enzyme that has been shown to act on a large number of these other oxidatively damaged DNA sites. A homologue of E. coli Endonuclease III, NTH is a DNA glycosylase with apurinic/apyrimidinic lyase activity. The NTH protein has broad substrate specificity, including numerous ring saturation and fragmentation products of pyrimidines. Research indicates NTH plays a crucial role in removal of oxidative base lesions in mitochondrial DNA., , Positive control: K562 cell extracts , Hela cell extracts.
