General description
钙调蛋白(CaM)是一种普遍存在的钙结合蛋白。CaM 在许多细胞类型中表达,并且可以具有不同的亚细胞定位,包括细胞质、细胞器内,或与质膜或细胞器膜结合。CaM 结合的许多蛋白质本身无法结合钙,因此将 CaM 用作钙传感器和信号传感器。CaM 还可以利用储存在内质网和肌质网中的钙。CaM 与钙结合后会发生构象变化,从而使其与特定蛋白质结合以产生特定反应。
Application
来自牛脑的钙调蛋白已用于研究牛主动脉内皮细胞颗粒和胞质组分中钙调蛋白相关的内皮源性舒张因子/一氧化氮合酶活性。它还用作体积排阻色谱的标准品。
Biochem/physiol Actions
钙调蛋白(CaM)可以结合并调节多种不同的蛋白质靶标,从而影响多种不同的细胞功能。它参与炎症、新陈代谢、细胞凋亡、肌肉收缩、细胞内运动、短期和长期记忆、神经生长和免疫反应。CaM 最多可以结合四个钙离子,并且可以进行翻译后修饰,例如磷酸化、乙酰化、甲基化和蛋白水解,每种都可能调节其作用。
