NTHL1 Q90TER (NTHL1 Q90*) truncation mutant (Weren et al. 2015) lacks the DNA binding domain and the glycosylase domain and is thus predicted to be unable to recognize and bind damaged DNA, including damaged DNA containing thymine glycol (Tg), although this has not been experimentally tested. NTHL1 Q287TER (NTHL1 Q287*) truncation mutant (Broderick et al. 2017) lacks a portion of the DNA binding domain, including glutamine residue Q287, important for substrate recognition (Robey-Bond et al. 2017) and is predicted to be unable to recognize and bind damaged DNA, including damaged DNA containing thymine glycol (Tg), although this has not been experimentally tested.
