功能概要

该基因编码的蛋白质属于 TDG/mug DNA 糖基化酶家族。胸腺嘧啶 DNA 糖基化酶 (TDG) 通过水解 DNA 的糖磷酸主链和错配的胸腺嘧啶之间的碳氮键,从 G/T 错配中去除胸腺嘧啶部分。由于活性较低,这种酶还可以从 C/T 和 T/T 错配中去除胸腺嘧啶。 TDG 还可以去除与鸟嘌呤错配的尿嘧啶和 5-溴尿嘧啶。这种酶在细胞防御由 5-甲基胞嘧啶和胞嘧啶的自发脱氨作用引起的基因突变中起着核心作用。该基因可能在 12 号染色体的 p 臂中有一个假基因。[RefSeq 提供,2008 年 7 月]

The protein encoded by this gene belongs to the TDG/mug DNA glycosylase family. Thymine-DNA glycosylase (TDG) removes thymine moieties from G/T mismatches by hydrolyzing the carbon-nitrogen bond between the sugar-phosphate backbone of DNA and the mispaired thymine. With lower activity, this Enzyme also removes thymine from C/T and T/T mispairings. TDG can also remove uracil and 5-bromouracil from mispairings with guanine. This Enzyme plays a central role in cellular defense against genetic mutation caused by the spontaneous deamination of 5-methylcytosine and cytosine. This gene may have a pseudogene in the p arm of chromosome 12. [provided by RefSeq, Jul 2008]
