INPPL1 (Inositol Polyphosphate Phosphatase-Like 1): INPPL1, also known as SHIP2 (Src Homology 2 domain-containing Inositol Phosphatase 2), is a phosphatase that plays a crucial role in the regulation of phosphoinositide signaling pathways, which are integral to various cellular processes such as proliferation, survival, and migration. This enzyme specifically dephosphorylates the 5' position of the inositol ring in phosphatidylinositol 3,4,5-trisphosphate (PIP3), thereby acting as a negative regulator of the PI3K (phosphoinositide 3-kinase) signaling pathway. INPPL1's activity is implicated in the modulation of insulin signaling and glucose homeostasis, making it a significant player in metabolic regulation and a potential target for the...
