Phosphatidylinositol 3-kinase regulatory subunit beta is an enzyme that in humans is encoded by the PIK3R2 gene.[1][2]


Interactions[edit]

PIK3R2 has been shown to interact with FYN,[3] HER2/neu,[3] Epidermal growth factor,[3] Cbl gene,[4][5] PIK3CD,[6] CRKL[7] and Macrophage colony-stimulating factor.[3]
