El fosfatidilinositol 3,5-bifosfato (PI(3,5)P2) es uno de los componentes fosfolipídicos de la membrana celular así como de la membrana de orgánulos. Los fosfoinosítidos más importantes son los del grupo fosfatidilinositol bifosfato.​ Cuando determinados ligandos se unen a receptores de la membrana. Fosfatidilinositol 3,4-bifosfato. Quite the same Wikipedia. Just better.
