C9ORF72突变是肌萎缩性侧索硬化症(ALS)和额颞叶变性(FTD)中最常见的缺陷。C9ORF72的单倍不足与六核苷酸重复扩增一起导致神经元功能障碍。我们用冷冻电镜(cro - em)测定了C9orf72-SMCR8-WDR41配合物的结构。C9orf72和SMCR8都是longin-DENN结构域蛋白,而WDR41是一种β -螺旋桨蛋白,与SMCR8结合,使整个结构类似于眼滑钩。氨基酸饥饿中WDR41和SMCR8DENN的接触驱动溶酶体定位。该结构提示C9orf72-SMCR8是一个小的GTPase激活蛋白(GAP)。我们发现C9orf72-SMCR8-WDR41是Arf家族小GTPases的GAP。这些数据合理化了C9orf72在正常生理和ALS/FTD中的功能。
Mutation of C9ORF72 is the most prevalent defect in amyotrophic lateral sclerosis (ALS) and frontal temporal degeneration (FTD). Together with hexanucleotide repeat expansion, haploinsufficiency of C9ORF72 contributes to neuronal dysfunction. We determined the structure of the C9orf72-SMCR8-WDR41 complex by cryo-EM. C9orf72 and SMCR8 are both longin-DENN domain proteins, while WDR41 is a beta-propeller protein that binds to SMCR8 such that the whole structure resembles an eye slip hook. Contacts between WDR41 and SMCR8DENN drive lysosomal localization in amino acid starvation. The structure suggested that C9orf72-SMCR8 was a small GTPase activating protein (GAP). We found that C9orf72-SMCR8-WDR41 is a GAP for Arf family small GTPases. These data rationalize the function of C9orf72 both in normal physiology and in ALS/FTD.
