描述：

Description: 
Human NEIL1 acts as both an N-glycosylase and an AP-lyase. The N-glycosylase activity releases oxidized pyrimidines and purines from double-stranded DNA, generating an apurinic (AP site). The AP-lyase activity cleaves 3´ and 5´ to the AP site leaving a 5´ phosphate and a 3´ phosphate. Damaged bases recognized and removed by hNEIL1 include thymine glycol, 5,6-dihydrothymine, 5,6-dihydroxyuracil, 5-hydroxycytosine, 5-hydroxyuracil, 5-formyluracil, 8oxo-guanine opposite C, T or G, 4,6-diamino-5-formamidopyrimidine and 2,6-diamino-4-hydroxy-5-formamidopyrimidine (1,2).
Source:
An E. coli strain that carries the cloned human NEIL1 gene.

注意事项：

Compared to the activity on AP-site, hNEIL1 has ≥ 50% activity on thymine glycol and ≥ 25% activity on dhU, dhT, 5hoU and 5hoC. hNEIL1 is active on 8oxoG opposite C,T and G, but is not active on an 8oxoG:A base pair. hNEIL1 is not active on 5-hydroxymethyluracil.
