背景 | α-actinin belongs to the spectrin family of cytoskeletal proteins. It was first recognized as an actin cross-linking protein, forming an antiparallel homodimer with an actin binding head at the amino terminus of each monomer. More recently, α-actinin has been shown to interact with a large number of proteins involved in signaling to the cytoskeleton including those involved in cellular adhesion, migration and immune cell targeting. (1). The interaction of α-actinin with ICAM5 (intercellular adhesion molecule-5) helps to promote neurite outgrowth (2). In osteoblasts, interaction of α-actinin with integrins stabilizes focal adhesions and may protect cells from apoptosis (3). Isoforms 1 and 4 of α-actinin, which are non-muscle isoforms, are present in stress fibers, sites of adhesion and intercellular contacts, filopodia and lamellipodia. The muscle isoforms 2 and 3 localize to the Z-discs of striated muscle and to dense bodies and plaques in smooth muscle (1).α-actinin蛋白属于细胞骨架蛋白的血影蛋白家族。其首先被确认作为一个actin交联蛋白,与actin蛋白每个单体的氨基末端的连接头形成一个反向平行的二聚体。最近,α-actinin蛋白已经研究显示与大量蛋白相互作用,其涉及到细胞骨架信号包括细胞粘附、迁移及免疫细胞定位(1)。α-actinin蛋白与ICAM5 (intercellular adhesion molecule-5)的相互作用有助于促进轴突生长(2)。在成骨细胞中,α-actinin与integrins的相互作用稳定粘着斑,并且有助于阻止细胞凋亡(3)。 α-actinin蛋白的亚型1和4是非肌肉特异性亚型,它们存在于应力纤维,粘连的部位和细胞间的接触,丝状伪足和片状伪足。肌肉特异性亚型2和3定位于横纹肌Z-discs、致密体和平滑肌斑块(1)。 |
