一般描述
尽管PI(4,5)P2是细胞膜的微量组成成分,但它作为许多重要信号蛋白的底物起着关键作用。PI(4,5)P2是IP3/DAG途径中的中间体,其中它被磷脂酶C水解以释放第二信使,肌醇-1,4,5-三磷酸(IP3)和二酰基甘油(DAG)。PI(4,5)P2也是PI 3-激酶的底物,其可被磷酸化为PI(3,4,5)P3,从而作为下游信号组分,例如蛋白激酶AKT的激活剂。
磷脂酰肌醇是一种结构性磷脂。磷脂酰肌醇磷酸(PIP)位于质膜中。
应用
18:1 PI(4,5)P2可用作天然巨噬细胞膜的添加剂,以生成富含磷脂的膜脂质体。它还可用于:
- 制备阴离子磷脂脂质体
- 作为支撑膜管 (SMrT) 模板的成分
- 用于脂质体制备
生化/生理作用
磷脂酰肌醇二磷酸盐 (PIP2) 可以有效地刺激ATP酶。
