[Abstract]  A mitochondrion is a dynamic intracellular organelle that actively divides and fuses to control its size, number and shape in cells. A regulated balance between mitochondrial division and fusion is fundamental to the function, distribution and turnover of mitochondria (Roy et al., 2015). Mitochondrial division is mediated by dynamin-related protein 1 (Drp1), a mechano-chemical GTPase that constricts mitochondrial membranes (Tamura et al., 2011). Mitochondrial membrane lipids such as phosphatidic acid and cardiolipin bind Drp1, and Drp1-phospholipid interactions provide key regulatory mechanisms for mitochondrial division (Montessuit et al., 2010; Bustillo-Zabalbeitia et al., 2014; Macdonald et al., 2014; Stepanyants et al., 2015; ... [摘要]  线粒体是一种动态的细胞内细胞器,主动分裂和融合以控制细胞的大小,数量和形状。线粒体分裂和融合之间的调节平衡是线粒体功能,分布和周转的基础(Roy等,2015)。线粒体分化是由动力蛋白相关蛋白1(Drp1)介导的,其是限制线粒体膜的机械化学GTP酶(Tamura等人,2011)。线粒体膜脂质如磷脂酸和心磷脂结合Drp1,并且Drp1磷脂相互作用提供线粒体分裂的关键调控机制(Montessuit等人,2010; Bustillo-Zabalbeitia等人2014年; Macdonald等人,2014年; Stepanyants等人,2015; Adachi等人,2016)。在这里,我们描述了使用纯化的重组Drp1和具有定义的一组磷脂的合成脂质体定量测量Drp1与脂质的相互作用的生物化学实验。该测定使得可以定义蛋白质 - 脂质相互作用的特异性以及头基和酰基链的作用。

背景 蛋白质和膜脂质的相互作用对于细胞如细胞器分裂中生物膜的重塑至关重要。在线粒体分裂中,Drp1限制线粒体膜并驱动该膜重塑过程。我们最近显示,信号磷脂,磷脂酸与Drp1相互作用,并通过限制线粒体上的组装分裂机制(Adachi等人,2016)产生启动步骤。 Drp1识别磷脂酸的头基和酰基链。为了分析Drp1-磷脂酸结合,我们建立了几种蛋白质 - ...

[Abstract]  This is a protocol to detect lipid transfer activity of NRF-5, a member of the LPS binding/lipid transfer protein family. The lipid transfer activity is examined by using isotope-labeled cholesterol and liposomes, and tested in two directions (Figure 1): from proteins to liposomes and from liposomes to proteins. [摘要]  这是一种检测NRF-5(LPS结合/脂质转移蛋白家族成员)的脂质转移活性的方案。 通过使用同位素标记的胆固醇和脂质体检查脂质转移活性,并在两个方向(图1)测试:从蛋白质到脂质体,从脂质体到蛋白质。
