PI31

PI31 refers to a specific protein, also known as Phosphoinositide-binding protein 1 or PBPI. It is a protein involved in cellular processes. Research indicates that PI31 plays a role in lipid metabolism and the regulation of membrane trafficking. Specifically, it is known to bind to phosphatidylinositol phosphates, which are crucial signaling molecules found in cell membranes. This binding activity suggests a function in organizing or mediating interactions at the membrane. Studies have explored its involvement in pathways related to cell growth and survival. The exact mechanisms and full spectrum of PI31's functions are still areas of ongoing scientific investigation. Its presence and activity have been observed in various cell types and tissues.
