Phosphatidylinositol 3-phosphate recognition and membrane docking by the FYVE domain.

ABSTRACT: The FYVE domain is a small zinc binding module that recognizes phosphatidylinositol 3-phosphate [PtdIns(3)P], a phospholipid enriched in membranes of early endosomes and other endocytic vesicles. It is usually present as a single module or rarely as a tandem repeat in eukaryotic proteins involved in a variety of biological processes including endo- and exocytosis, membrane trafficking and phosphoinositide metabolism. A number of FYVE domain-containing proteins are recruited to endocytic membranes through the specific interaction of their FYVE domains with PtdIns(3)P. Structures and PtdIns(3)P binding modes of several FYVE domains have recently been characterized, shedding light on the molecular basis underlying multiple cellular functions of these proteins. Here, structural and functional
