骨骼肌肌动蛋白α1（英语：Skeletal muscle, actin alpha 1）是一种在人类中由ACTA1基因编码的蛋白质。^[6]^[7]

在骨骼肌中表达的肌动蛋白α1是已鉴定的六种不同肌动蛋白亚型之一。肌动蛋白是高度保守的蛋白质，它们参与细胞运动、结构和完整性。α肌动蛋白是收缩装置的主要成分。^[8]

骨骼肌肌动蛋白基因表达

骨骼α肌动蛋白的表达是由已知会导致肌肉形成的刺激和条件诱导的。^[9]这种情况导致定型细胞（卫星细胞）融合到肌管中，形成肌纤维。骨骼肌动蛋白本身在表达时会引起其他几种“生肌基因”的表达，这些基因对肌肉形成至关重要。^[10]激活骨骼肌动蛋白基因表达的一个关键转录因子是血清反应因子，一种结合肌动蛋白基因启动子DNA上特定位点的蛋白质。^[11]血清反应因子可以将许多其他蛋白质带到骨骼肌动蛋白的启动子，例如雄激素受体，从而有助于通过雄激素（通常称为合成代谢）类固醇诱导骨骼肌动蛋白基因表达。^[12]

相互作用

肌动蛋白α1已被证明与TMSB4X、^[13]^[14]MIB2^[15]和PRKCE产生相互作用。^[16]
