After endocytosis, endosomes fuse with one another. One targeting factor appears to be the production of phosphatidylinositol 3-phosphate in membranes; this lipid head group is then recognized by so-called FYVE domains found on some endosomal fusion proteins. Kutateladze and Overduin present an analysis of the structure of the FYVE domain of early endosome antigen 1 in complex with phosphatidylinositol 3-phosphate and suggest a mechanism by which these interactions may promote endosome recognition. For an excellent overview on how FYVE domains function in signaling, read the STKE perspective by Corvera.
