NMR Structure(hide GO term definitions)
Chain A,B   (ZO2_HUMAN | Q9UDY2)
molecular function
    GO:0004385    guanylate kinase activity    Catalysis of the reaction: ATP + GMP = ADP + GDP.
    GO:0008022    protein C-terminus binding    Interacting selectively and non-covalently with a protein C-terminus, the end of any peptide chain at which the 1-carboxy function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0030674    protein binding, bridging    The binding activity of a molecule that brings together two or more protein molecules, or a protein and another macromolecule or complex, through a selective, non-covalent, often stoichiometric interaction, permitting those molecules to function in a coordinated way.
    GO:0019904    protein domain specific binding    Interacting selectively and non-covalently with a specific domain of a protein.
biological process
    GO:0046710    GDP metabolic process    The chemical reactions and pathways involving GDP, guanosine 5'-diphosphate.
    GO:0046037    GMP metabolic process    The chemical reactions and pathways involving GMP, guanosine monophosphate.
    GO:0071847    TNFSF11-mediated signaling pathway    A series of molecular signals initiated by the binding of tumor necrosis factor ligand superfamily member 11 (TNFSF11) to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.
    GO:0090557    establishment of endothelial intestinal barrier    The establishment of a barrier between endothelial cell layers of the intestine to exert specific and selective control over the passage of water and solutes, thus allowing formation and maintenance of compartments that differ in fluid and solute composition.
    GO:0035329    hippo signaling    The series of molecular signals mediated by the serine/threonine kinase Hippo or one of its orthologs. In Drosophila, Hippo in complex with the scaffold protein Salvador (Sav), phosphorylates and activates Warts (Wts), which in turn phosphorylates and inactivates the Yorkie (Yki) transcriptional activator. The core fly components hippo, sav, wts and mats are conserved in mammals as STK4/3 (MST1/2), SAV1/WW45, LATS1/2 and MOB1.
    GO:0050892    intestinal absorption    Any process in which nutrients are taken up from the contents of the intestine.
    GO:2001205    negative regulation of osteoclast development    Any process that stops, prevents or reduces the frequency, rate or extent of osteoclast development.
    GO:0090559    regulation of membrane permeability    Any process that modulates the frequency, rate or extent of the passage or uptake of molecules by a membrane.
    GO:0010033    response to organic substance    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an organic substance stimulus.
cellular component
    GO:0005912    adherens junction    A cell junction at which anchoring proteins (cadherins or integrins) extend through the plasma membrane and are attached to actin filaments.
    GO:0005923    bicellular tight junction    An occluding cell-cell junction that is composed of a branching network of sealing strands that completely encircles the apical end of each cell in an epithelial sheet; the outer leaflets of the two interacting plasma membranes are seen to be tightly apposed where sealing strands are present. Each sealing strand is composed of a long row of transmembrane adhesion proteins embedded in each of the two interacting plasma membranes.
    GO:0030054    cell junction    A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
