Phosphatidylinositol 3-kinases (PI3Ks) are a family of enzymes that catalyze the phosphorylation of phosphatidylinositol at the D-3 position of the inositol ring, serving critical functions in cellular signaling pathways. Among them, the isoform PI3K class II γ (PI3KC2γ), which is predominantly expressed in the liver, regulates hepatic glycogen synthesis and thus plays a critical role in glucose homeostasis.
