ACTN2(α-actinin-2)是一种肌动蛋白结合蛋白,属于α-actinin基因家族,该家族包括ACTN1、ACTN2、ACTN3和ACTN4。这些基因编码的蛋白质具有相似的结构和功能,主要通过与肌动蛋白(actin)结合参与细胞骨架的组装和稳定。ACTN2主要在骨骼肌和心肌中表达,其功能包括维持肌节的稳定性、调节肌肉收缩以及参与细胞信号传导。ACTN2蛋白包含一个N端的肌动蛋白结合域、一个中央的杆状结构域和C端的钙调蛋白样结构域,这些结构域使其能够交联肌动蛋白纤维并连接到其他细胞骨架蛋白。ACTN2的突变可能导致肌节结构异常,进而引发肌肉疾病,如扩张型心肌病(DCM)和肥厚型心肌病(HCM)。这些突变通常影响蛋白质的稳定性或与其他蛋白的相互作用,导致心肌收缩功能受损。此外,ACTN2的表达水平变化也与某些疾病相关。过表达ACTN2可能增强肌肉的收缩能力,但可能导致心肌肥厚或纤维化;而降低表达则可能引起肌无力或心肌功能减退。ACTN2还与Z盘(Z-disc)的形成有关,Z盘是肌节的重要组成部分,负责传递收缩力。在ACTN2缺失或功能异常的情况下,Z盘结构可能紊乱,影响肌肉的整体功能。ACTN2的某些突变已被发现与家族性心肌病相关,表明其在心脏健康中的关键作用。此外,ACTN2与其他肌节蛋白如肌联蛋白(titin)和肌球蛋白(myosin)相互作用,共同维持肌肉的结构和功能。α-actinin基因家族的共性在于它们都参与细胞骨架的组装和稳定,并在肌肉和非肌肉细胞中发挥重要作用。总的来说,ACTN2在肌肉结构和功能中扮演重要角色,其突变或表达异常可能导致严重的肌肉或心脏疾病。

Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. In nonmuscle cells, the cytoskeletal isoform is found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. This gene encodes a muscle-specific, alpha actinin isoform that is expressed in both skeletal and cardiac muscles. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2013]

Alpha的actinins属于血影基因超家族代表不同群体的细胞骨架蛋白,包括α和βspectrins和dystrophins。阿尔法辅肌动蛋白是用在不同的细胞类型的多个角色的肌动蛋白结合蛋白。在非肌肉细胞中,细胞骨架同种型是沿着微丝束和粘着型结,它是参与结合肌动蛋白的膜中发现。与此相反,骨骼肌,心肌,和平滑肌亚型被定位于Z盘和类似的致密体,在那里它们帮助锚定的肌原纤维肌动蛋白丝。这个基因编码在两个骨骼肌和心肌中表达的肌肉特异性,α-辅肌动蛋白同种型。已发现该基因编码不同亚型的几个抄本变形。 [由RefSeq的,2013年5月提供]
