Along with pleckstrin homology (PH) and phox homology (PX) domains, FYVE domains are the principal readers of the phosphoinositide (PI) code that mediate specific recognition of eukaryotic organelles. Of all the human FYVE domain-containing proteins, those within the Faciogenital dysplasia (Fgd) subfamily are particularly divergent, and couple with GTPases to exert unique cellular functions.
