双切口在 GG-NER 中的机制
中文名称
通路描述
双切口在受损 DNA 链上切除包含损伤的寡核苷酸,从开放泡中将其移除。切除的寡核苷酸长约 27-30 个碱基。5' 侧相对于损伤位点的切口由 ERCC1:ERCC4 内切酶执行,在损伤位点 3' 侧的切口由 ERCC5 内切酶执行(Staresincic 等人,2009 年)。
英文描述
Dual Incision in GG-NER Double incision at the damaged DNA strand excises the oligonucleotide that contains the lesion from the open bubble. The excised oligonucleotide is ~27-30 bases long. Incision 5' to the damage site, by ERCC1:ERCC4 endonuclease, precedes the incision 3' to the damage site by ERCC5 endonuclease (Staresincic et al. 2009).
