细胞核与肌动蛋白细胞骨架相连,用于控制其在细胞中的位置和机械化学信号传导。 Nesprin-2G 是连接细胞核与肌动蛋白细胞骨架的主要外核膜蛋白之一。除了成对的钙调蛋白同源 (CH) 结构域外,nesprin-2G 还通过结合肌动蛋白捆绑蛋白 FHOD1 和肌成束蛋白与肌动蛋白丝相互作用。我们描述了使用肌动蛋白共沉测定法测量 nesprin-2G 与肌动蛋白丝相互作用的方法,并使用 GST pull-down 方法测量其结合伴侣 FHOD1 的相互作用。
Nuclei are connected to the actin cytoskeleton for controlling its position in the cell and for mechanochemical signaling. Nesprin-2G is one of the major outer nuclear membrane proteins that links the nucleus to the actin cytoskeleton. In addition to its paired calponin homology (CH) domains, nesprin-2G interacts with actin filaments by binding the actin-bundling proteins FHOD1 and fascin. We describe methods to measure the interaction of nesprin-2G with actin filaments using an actin co-sedimentation assay and with its binding partner FHOD1 using a GST pull-down method.
