Chain A   (OCLN_HUMAN | Q16625)
molecular function
    GO:0008757    S-adenosylmethionine-dependent methyltransferase activity    Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate.
    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:0019904    protein domain specific binding    Interacting selectively and non-covalently with a specific domain of a protein.
    GO:0008119    thiopurine S-methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + a thiopurine = S-adenosyl-L-homocysteine + a thiopurine S-methylether.
biological process
    GO:0046498    S-adenosylhomocysteine metabolic process    The chemical reactions and pathways involving S-adenosylhomocysteine; the L-enantiomer is formed from S-adenosylmethionine and is a strong inhibitor of S-adenosylmethionine-mediated methylation reactions. It can be cleaved to form adenosine and homocysteine.
    GO:0046500    S-adenosylmethionine metabolic process    The chemical reactions and pathways involving S-adenosylmethionine, S-(5'-adenosyl)-L-methionine, an important intermediate in one-carbon metabolism.
    GO:0070830    bicellular tight junction assembly    The aggregation, arrangement and bonding together of a set of components to form a 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.
    GO:0045216    cell-cell junction organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a cell-cell junction. A cell-cell junction is a specialized region of connection between two cells.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0006461    protein complex assembly    The aggregation, arrangement and bonding together of a set of components to form a protein complex.
cellular component
    GO:0016324    apical plasma membrane    The region of the plasma membrane located at the apical end of the cell.
    GO:0016327    apicolateral plasma membrane    The apical end of the lateral plasma membrane of epithelial cells.
    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:0005911    cell-cell junction    A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals.
    GO:0031410    cytoplasmic vesicle    A vesicle found in the cytoplasm of a cell.
    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:0030139    endocytic vesicle    A membrane-bounded intracellular vesicle formed by invagination of the plasma membrane around an extracellular substance. Endocytic vesicles fuse with early endosomes to deliver the cargo for further sorting.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    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.
