INPPL1 (Inositol Polyphosphate Phosphatase-Like 1): INPPL1, also known as SHIP2 (Src Homology 2 domain-containing Inositol Phosphatase 2), is an enzyme crucial for regulating phosphoinositide signaling pathways in the body. These pathways are vital for controlling cellular functions such as proliferation, survival, and migration. INPPL1 specifically removes a phosphate group from the 5' position of phosphatidylinositol 3,4,5-trisphosphate (PIP3), serving as a negative regulator of the PI3K (phosphoinositide 3-kinase) signaling pathway. Its function is essential for modulating insulin signaling and maintaining glucose homeostasis, making it a key player in metabolic regulation and a promising therapeutic target.
