Background: Clathrin-coated vesicles provide for the intracellular transport of cargo proteins following endocytosis and during multiple vesicle trafficking pathways. Vesicles form at specialized areas of the cell membrane where clathrin and associated proteins form clathrin-coated pits. Invagination of these cell membrane-associated pits internalizes proteins and forms an intracellular clathrin-coated vesicle (1,2). Clathrin is the most abundant protein in these vesicles and is present as a basic assembly unit called a triskelion. Each clathrin triskelion is composed of three clathrin heavy chains and three clathrin light chains. Clathrin heavy chain proteins are composed of several functional domains, including a carboxy-terminal region that permits interaction with other heavy chain proteins within a triskelion, and a globular amino-terminal region that associates with other vesicle proteins (2). Adaptor proteins, such as AP2, epsin and EPS15, are responsible for the recruitment of vesicle proteins to sites of pit formation and the assembly of the clathrin-coated vesicle. Following vesicle invagination, the GTPase dynamin constricts the neck of the nascent vesicle to complete formation of the free, cytosolic vesicle (3,4).

Background: OCRL1 is an inositol 5-phosphatase that selectively dephosphorylates the 5 position of the inositol ring. Its substrates include phosphatidylinositol 4,5-bisphosphate, inositol 1,4,5-trisphosphate, and inositol 1,3,4,5-tetrakisphosphate (1). Research studies indicate that mutations in OCRL1 are linked to Oculocerebrorenal syndrome or Lowe syndrome, an X-linked disorder distinguished by mental retardation and congenital cataracts, as well as Dent's disease (2,3). OCRL1 interacts with several endocytic proteins, including clathrin, AP-2, and RabGTPases (4-7). OCRL1 is localized to the Golgi complex, endosomes, and late stage clathrin-coated pits (6,8). OCRL1 controls early endosome function (8), regulating membrane traffic from endosomes to the Golgi. It is also involved in cytokinesis (9) and cilia assembly (10).
