该基因编码dna糖基化酶fpg/nei家族的一个成员。这些碱基通过切割氧化损伤的碱基并通过它们的脱氧核糖核酸裂解酶活性引入DNA链断裂来启动碱基切除修复的第一步。这种酶主要与转录过程中的dna修复有关，并在胞嘧啶衍生的损伤，特别是5-羟基尿嘧啶和5-羟基胞嘧啶的损伤中起作用。它包含一个N-末端催化结构域、一个铰链结构域和一个C-末端DNA结合结构域，该结合结构域具有螺旋双螺旋和锌指基序作为多蛋白dna修复复合物的一部分，该酶与x射线交叉互补因子1支架蛋白相互作用。这个基因的一个假基因已经被鉴定出来[由RefSeq提供，2017年3月]
This gene encodes a member of the Fpg/Nei family of DNA glycosylases. These glycosylases initiate the first step in base excision repair by cleaving oxidatively damaged bases and introducing a DNA strand break via their abasic site lyase activity. This enzyme is primarily associated with DNA repair during transcription and acts prefentially on cytosine-derived lesions, particularly 5-hydroxyuracil and 5-hydroxycytosine. It contains an N-terminal catalytic domain, a hinge region, and a C-terminal DNA-binding domain with helix-two-turn-helix and zinc finger motifs. This enzyme interacts with the X-ray cross complementing factor 1 scaffold protein as part of a multi-protein DNA repair complex. A pseudogene of this gene has been identified.
