| 产品介绍 | Nebulette binds to actin and plays an important role in Z-disk assembly. It is a cardiac homolog of nebulin and its expression is abundant in cardiac muscle. Nebulette defects are assocated with non-familial idiopathic cardiacmyopathy. Nebulin and nebulette are homologous thin-filament associated proteins expressed in skeletal and cardiac muscles, respectively. Nebulette, unlike nebulin, is confined to the Z-disc region of the sarcomere and does not span the whole thin filament length. Nebulette colocalizes with α-actinin in the pre-, nascent, and mature myofibrils. A polymorphism in the actin-binding motif of nebulette is a genetic marker of susceptibility to nonfamilial idiopathic dilated cardiomyopathy (IDC), characterized by a thin-walled heart and systolic dysfunction. Function: Binds to actin and plays an important role in the assembly of the Z-disk. Isoform 2 might play a role in the assembly of focal adhesion. Subunit: Isoform 2 interacts with ZYX (Zyxin). Subcellular Location: Cytoplasmic. Tissue Specificity: Abundantly expressed in cardiac muscle, but not in skeletal or smooth muscle. Localized to Z-lines in cardiac cells and to dense bodies in nonmuscle cells. Isoform 2 is expressed in non-muscle cells such as in fibroblasts. Similarity: Contains 23 nebulin repeats. Contains 1 SH3 domain.

文献和实验细胞中, 肌动蛋白也占细胞总蛋白的1~5%。 肌动蛋白是一种中等大小的蛋白质, 由375个氨基酸残基组成, 并且是由一个大的、高度保守的基因编码。单体肌动蛋白分子的分子量为43kDa, 其上有三个结合位点。一个是ATP结合位点, 另两个都是与肌动蛋白结合的结合蛋白结合位点。
由两个亚基组成的球形蛋白,它在膜骨架中的作用是通过同血影蛋白结合,促使血影蛋白同肌动蛋白结合。带4.1蛋白本身不同肌动蛋白相连,因为它没有与肌动蛋白连接的位点。
Cell:清华俞立团队首次发现迁移体介导的线粒体胞吐,一种新型线粒体质控过程
至质膜来介导线粒体胞吐,而 Myo19 则将线粒体束缚在与质膜紧密相关的皮质肌动蛋白上。最后,与皮质肌动蛋白结合的管状线粒体尖端经历 Drp1 介导的裂变,然后被转运至迁移体。图片来源:Cell与不发生迁移的细胞相比,迁移细胞需要消耗更多的能量来支持细胞迁移,因此它们可能具有更高的呼吸速率,更多的 ROS 生成和更高的线粒体压力负荷。透射电镜图像显示,迁移体中大多数线粒体基质浓缩和嵴肿胀,提示这些线粒体可能受到损伤。为了直接检验这一假设,该研究使用 MitoSOX 对细胞进行了染色,结果表明迁移体内
