ACTG1

肌动蛋白是高度保守的蛋白质，参与各种类型的细胞运动和维持细胞骨架。脊椎动物中肌动蛋白亚型主要有三类：α、β和γ。α肌动蛋白存在于肌肉组织中，是收缩装置的主要组成部分。β和γ-肌动蛋白在大多数细胞类型中共存，作为细胞骨架的组成部分，并作为细胞内运动的调节剂。肌动蛋白γ1，由该基因编码，是一种细胞质肌动蛋白，存在于所有细胞类型中。该基因突变与常染色体显性遗传非综合征感音神经进行性聋的一个亚型dfna20/26有关，也与baraitser-winter综合征有关。选择性剪接导致多个转录变体。[由RefSeq提供，2017年7月]
Actins are highly conserved proteins that are involved in various types of cell motility and in maintenance of the cytoskeleton. Three main groups of actin isoforms have been identified in vertebrate animals: alpha, beta, and gamma. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton and as mediators of internal cell motility. Actin gamma 1, encoded by this gene, is a cytoplasmic actin found in all cell types. Mutations in this gene are associated with DFNA20/26, a subtype of autosomal dominant non-syndromic sensorineural progressive hearing loss and also with Baraitser-Winter syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2017]
