INPPL1 (Inositol Polyphosphate Phosphatase-Like 1): INPPL1,also known as SHIP2 (Src Homology 2 domain-containing Inositol Phosphatase 2), is an enzyme that plays a key role in regulating phosphoinositide signaling pathways in the body. These pathways are essential for controlling cellular processes such as proliferation, survival, and migration. INPPL1 specifically removes a phosphate group from the 5' position of phosphatidylinositol 3,4,5-trisphosphate (PIP3), acting as a negative regulator of the PI3K (phosphoinositide 3-kinase) signaling pathway. Its activity is important for modulating insulin signaling and maintaining glucose balance, making it a significant factor in metabolic regulation and a potential therapeutic target.
