[Abstract]  Studying liquid-liquid phase separation (LLPS) of proteins provides key insights into the biogenesis of membraneless organelles and pathological protein aggregation in disease. We have established a protocol for inducing the phase separation of arginine-rich peptides, which allows for studying their molecular determinants and dynamics (Boeynaems et al., 2017). [摘要]  研究蛋白质的液 - 液相分离(LLPS)提供了无膜细胞器的生物发生和疾病中病理蛋白聚集的关键见解。 我们已经建立了诱导富含精氨酸的肽的相分离的方案,这允许研究其分子决定因素和动力学(Boeynaems等,2017)。
【背景】富含精氨酸的无序结构域通常存在于RNA结合蛋白中,包括与神经变性疾病相关的蛋白(例如FUS,FMRP,hnRNPA1)(Varadi等人,2015; Boeynaems等,2017)。 在携带C9orf72重复扩增的肌萎缩性侧索硬化患者中也产生有毒的富含精氨酸的重复肽(即polyGR和polyPR)(Kwon等,2014; Mizielinska等,2014; Varadi等,2015; Boeynaems et 等等,2016)。 (Kato et al。,2012; Burke et al。,2015; Lin et al。,2015; Molliex et al。,2015; Patel et al。,2015),虽然已经研究了不带电的低复杂度域的相分离, 开发了该方案来测试富含精氨酸的结构域是否也有助于相分离。 协议的示意图可以在图1中看到。
