Bifunctional DNA N-glycosylase with associated apurinic/apyrimidinic (AP) lyase function that catalyzes the first step in base excision repair (BER), the primary repair pathway for the repair of oxidative DNA damage. The DNA N-glycosylase activity releases the damaged DNA base from DNA by cleaving the N-glycosidic bond, leaving an AP site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination. Primarily recognizes and repairs oxidative base damage of pyrimidines. Has also 8-oxo-7,8-dihydroguanine (8-oxoG) DNA glycosylase activity. Acts preferentially on DNA damage opposite guanine residues in DNA. Is able to process lesions in nucleosomes without requiring or inducing nucleosome disruption.
基因功能參考文獻(xiàn):
The processing of the lesions was evaluated by purified enzyme cocktails of hNTH1 and hOGG1 as well as with a HeLa cell extract. Interestingly, the yield of double-strand breaks (DSBs) resulting from the processing of the bistranded lesions are appreciably lower when the DNA is treated with the HeLa cell extract compared with the relevant purified enzyme cocktail in both models PMID: 30207305
NTHL1 in these extracts was able to excise thymine glycol from both naked DNA and sites in nucleosomes that earlier studies had shown to be sterically accessible. However, the same extracts were able to excise lesions from sterically-occluded sites in nucleosomes only after the addition of Mg2+/ATP. PMID: 28709015
WT NTHL1 (human) and Nth (E. coli) are remarkably alike with respect to specificity of glycosylase reaction, and although NTHL1 is a much slower enzyme than Nth, the tighter binding of NTHL1 compensates, resulting in similar kcat/Kd values for both enzymes with each of the substrates tested. For NTHL1 Gln287Ala, specificity for substrates positioned opposite G is lost, but not that of substrates positioned opposite A. PMID: 28292631
We therefore found published evidence to support the association between variants in NTHL1 and RPS20 with CRC. PMID: 27713038
Both Ntg1 and its human homologue, NTHL1, can be SUMO-modified in response to oxidative stress. PMID: 27839712
NTH1 polymorphisms may be associated with non-small cell lung cancer pathogenesis. PMID: 26400813
This study extends the description of biallelic mutations in NTHL1 beyond the single c.268C-->T,p.Q90* mutation that was observed previously. PMID: 26559593
A homozygous loss-of-function germline mutation in the NTHL1 gene predisposes to a new subtype of BER-associated adenomatous polyposis and colorectal cancer. PMID: 25938944
we demonstrated that hNEIL1 and hNTH1 cleave Oz sites as efficiently as 5-hydroxyuracil sites. Thus, hNEIL1 and hNTH1 can repair Oz lesions PMID: 22465744
NTH1 is involved in removal of 8-oxoguanine from 8-oxoguanine/guanine mispairs in DNA PMID: 11328882
recombinant hNTH1 lacking 55, 72 or 80 residues from the N terminus had four- to fivefold higher activities than the full-length enzyme PMID: 12144783
substrate selectivity of mammalian NTH1 and the concomitant selective stimulation of activity by APE1 are indicative of selective repair of oxidative damage in different regions of the genome PMID: 12519758
dimerization of hNTH1 involving the N-terminal tail masks the inhibitory effect of this tail and plays a critical role in its catalytic turnover in the cell PMID: 14522981
hNTH1 and hNEIL1 but not hNEIL2 excised the two stereoisomers of thymine glycol (5R-Tg and 5S-Tg), but their isomer specificity was markedly different PMID: 14734554
search for the factors interacting with NTH1 shows GST-NTH1 fusion protein precipitates proliferating cell nuclear antigen (PCNA) and p53 as well as XPG from human cell-free extracts PMID: 15358233
NTH1 is a DNA glycosylase that excise 5-formyluracil, 5-hydroxymethyluracil and Thymine glycol in human cells. PMID: 15533839
hNTH1 plays two roles in the processing of radiation damages: repair of potentially lethal single lesions and generation of lethal double strand breaks at clustered damage sites. PMID: 16111924
Nth1 released 5R,6S 2'-deoxyribonucleoside diastereoisomer (Tg2) much more rapidly than cis 5S,6R-deoxyribonucleoside diastereoisomer (Tg1) regardless of the opposing purine. Neil1 released Thymine glycol non-stereoselectively. PMID: 16446124
The damage specificity of human homologues of Endo III (hNTHl) and Endo VIII (hNEIL1 and hNEIL2) is compared to elucidate the repair role in cells. PMID: 17150535
These observations suggest that access to sterically occluded lesions entails the partial, reversible unwrapping of DNA from the histone octamer, allowing hNTH1 to capture its DNA substrate when it is in an unwound state. PMID: 17923696
Downregulation of NTH1 is associated with gastric cancer. PMID: 19414504
