    Background

    Phosphoinositide 3-kinase (PI3K) catalyzes the production of phosphatidylinositol-3,4,5-triphosphate by phosphorylating phosphatidylinositol (PI), phosphatidylinositol-4-phosphate (PIP) and phosphatidylinositol-4,5-bisphosphate (PIP2). Growth factors and hormones trigger this phosphorylation event, which in turn coordinates cell growth, cell cycle entry, cell migration, and cell survival (1). PTEN reverses this process, and the PI3K signaling pathway is constitutively activated in human cancers that have loss of function of PTEN (2). PI3Ks are composed of a catalytic subunit (p110) and a regulatory subunit. Various isoforms of the catalytic subunit (p110α, p110β, p110γ, and p110δ) have been isolated, and the regulatory subunits that associate with p110α, p110β, and p110δ are p85α and p85β (3). In contrast, p110γ associates with a p101 regulatory subunit that is unrelated to p85. Furthermore, p110γ is activated by βγ subunits of heterotrimeric G proteins (4).

    • PI3K―Akt信号通路

      PI3K ― Akt 信号通路PI3K是一个复杂的大家族,根据其结构可分为3类:I型、Ⅱ型、Ⅲ型。 I型PI3K又分为IA和IB两个亚型,他们分别从酪氨酸激酶连接受体和G蛋白连接受体传递信号,其作用是催化磷脂酰肌醇(P1)在D3位的磷酸化,把底物PIP2转化为PIP3。IA型P13K是由催化亚单位Pll0和调节亚单位P85所组成的二聚体蛋白,具有类脂激酶和蛋白激酶的双重活性。在正常细胞中,P13K的活性是受许多机制严格控制的。一般认为,在静息细胞中,无活性的P85―P1lo复合物普遍

    • 经典信号通路之PI3K/AKT信号通路

      的I型PI3K. 哺乳动物 细胞中Ι型PI3K又分为IA和IB两个亚型, 他们分别从酪氨酸激酶连接受体和G蛋白连接受体传递信号.IA 型PI3K是由催化亚单位p110和调节亚单位p85所组成的二聚体蛋白, 具有类脂激酶和蛋白激酶的双重活性.PI3K通过两种方式激活, 一种是与具有磷酸化酪氨酸残基的生长因子受体或连接蛋白相互作用, 引起二聚体构象改变而被激活; 另一种是通过Ras和p110直接结合导致PI3K的活化. PI3K激活的结果是在质膜上产生第二信使PIP3, PIP3与细胞内含有PH结构

    • 【求助】如何用免疫沉淀法测定PI3K活性?

      -1000.htm 原理参见试剂盒说明书。 yys700714 谢谢,这个是测定活性的么?好做么?对样本要求如何?能否将您的体会详细告之。我是新手,不懂的好多。非常感谢!! yhwangcams 用这个试剂盒可以通过体外实验检测PI3-kinase的活性。 原理是首先利用免疫沉淀法得到PI3K复合物,然后用PI3K体外催化PIP2为PIP3,最后使用ELISA检测PIP3的水平,进而反映PI3-kinase的活性
