信号脂质磷脂酰肌醇3，4，5，三磷酸（PIP 3）是许多重要细胞过程（包括生长、存活和代谢）的必需介质。PIP 3通过I类磷酸肌醇3-激酶（PI 3 K）的作用产生，并且它们的活性通过与调节蛋白和活化刺激的相互作用而受到严格控制。IA类PI 3 K由三种不同的p110催化亚基（p110α、p110β和p110δ）组成，由于细胞表面受体下游的表达和接合的差异，它们在特定组织中发挥不同的作用。PI 3 K调节的破坏是许多人类疾病的常见驱动因素。编码IA类PI 3 K的p110α催化亚基的PIK 3CA基因中的激活突变在几种癌症类型中经常发生突变，并且已在原发性免疫缺陷患者中鉴定出编码p110δ催化亚基的PIK 3CD基因中的突变。所有IA类p110亚基与p85调节亚基相互作用，并且在癌症和原发性免疫缺陷中已经鉴定出不同p85调节亚基中的突变/缺失。本文综述了p85调节亚基对IA类PI 3 K催化活性的调节作用，以及PI 3 K催化亚基PIK 3CA、PIK 3CD（p110α、p110δ）和调节亚基PIK 3R 1（p85α）的激活突变如何介导PI 3 K活化和人类疾病的分子基础。
The signaling lipid phosphatidylinositol 3,4,5, trisphosphate (PIP3) is an essential mediator of many vital cellular processes, including growth, survival, and metabolism. PIP3 is generated through the action of the class I phosphoinositide 3-kinases (PI3K), and their activity is tightly controlled through interactions with regulatory proteins and activating stimuli. The class IA PI3Ks are composed of three distinct p110 catalytic subunits (p110α, p110β, and p110δ), and they play different roles in specific tissues due to disparities in both expression and engagement downstream of cell-surface receptors. Disruption of PI3K regulation is a frequent driver of numerous human diseases. Activating mutations in the PIK3CA gene encoding the p110α catalytic subunit of class IA PI3K are frequently mutated in several cancer types, and mutations in the PIK3CD gene encoding the p110δ catalytic subunit have been identified in primary immunodeficiency patients. All class IA p110 subunits interact with p85 regulatory subunits, and mutations/deletions in different p85 regulatory subunits have been identified in both cancer and primary immunodeficiencies. In this review, we will summarize our current understanding for the molecular basis of how class IA PI3K catalytic activity is regulated by p85 regulatory subunits, and how activating mutations in the PI3K catalytic subunits PIK3CA and PIK3CD (p110α, p110δ) and regulatory subunits PIK3R1 (p85α) mediate PI3K activation and human disease.
