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).

Background: Mammalian sterile-20-like (MST) kinases are upstream regulators of mitogen-activated protein kinase (MAPK) signaling pathways that regulate multiple biological processes, including apoptosis, morphogenesis, cell migration, and cytoskeletal rearrangements (1). This group of serine/threonine kinases includes a pair of closely related proteins (MST1, MST2) that are functionally distinct from the more distantly related MST3 and MST4 kinases. All four MST kinases share a conserved amino-terminal kinase domain and carboxy-terminal regulatory and interaction domains (1-3). At least three of these kinases (MST1-3) promote apoptosis and are activated by caspase cleavage followed by nuclear translocation of the active kinase. MST1/2 kinases play a key role in the Hippo signaling pathway, an evolutionarily conserved program that controls organ size by regulating cell proliferation, apoptosis, and stem cell self renewal (4).Mammalian Sterile 20-like kinase 4 (MST4, STK26, MASK) is a Golgi-localized kinase that is cleaved by caspase-3 in vitro. While its potential role in apoptosis is unclear, research studies indicate that MST4 is involved in MAPK and EGF pathway signaling (5,6). MST4 and the serine/threonine kinase YSK1 (STK25) localize to the Golgi apparatus following association with the Golgi scaffold protein GM130. Binding to GM130 activates MST4 through autophosphorylation at Thr178 (7).

Background: Members of the ADAM (a disintegrin and a metalloprotease) family of multidomain membrane proteins influence cell signaling and adhesion by shedding cell surface proteins, such as cytokines and growth factors. This process influences cell-extracellular matrix (ECM) adhesion and ECM remodeling. Conserved domains found in most ADAM family proteins include a prodomain, a zinc-dependent metalloprotease domain, a disintegrin domain, a carboxy-terminal cysteine-rich domain, an EGF-like sequence, and a short cytoplasmic tail (1,2).The ADAM metallopeptidase domain 10 (ADAM10) is a plasma membrane proteinase that cleaves membrane-bound proteins targeted for regulated intramembrane proteolysis (RIP). The ADAM10 prodomain acts as a chaperone that stabilizes mature ADAM protein folding, and prevents target-protein shedding through inhibition of ADAM10 proteinase activity (3,4). Mature ADAM10 is the major α-secretase responsible for cleavage of Notch, APP, cadherins, and prion protein (5-7). The ADAM10 protein cleaves receptor tyrosine kinases and their associated ligands and displays a wide range of regulatory functions across related signaling pathways (8). Research studies using knockout mice demonstrate that loss of ADAM10 results in defects in cortex formation, lymphocyte development, and cardiovascular development (9-11). Increased ADAM10 protein expression correlates with progression of many types of cancer (i.e. gastric cancer, hepatocellular carcinoma, and brain glioma), due to increased cancer cell migration, metastasis, and invasion (12-14). Mutations in the corresponding ADAM10 gene result in a rare, autosomal dominant pigmentation disorder known as reticulate acropigmentation of Kitamura (15).
