NMR Structure(hide GO term definitions)
Chain A   (TWF1_MOUSE | Q91YR1)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0003779    actin binding    Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments.
    GO:0003785    actin monomer binding    Interacting selectively and non-covalently with monomeric actin, also known as G-actin.
    GO:0005546    phosphatidylinositol-4,5-bisphosphate binding    Interacting selectively and non-covalently with phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions.
    GO:0032403    protein complex binding    Interacting selectively and non-covalently with any protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0004713    protein tyrosine kinase activity    Catalysis of the reaction: ATP + a protein tyrosine = ADP + protein tyrosine phosphate.
biological process
    GO:0051016    barbed-end actin filament capping    The binding of a protein or protein complex to the barbed (or plus) end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits.
    GO:0030837    negative regulation of actin filament polymerization    Any process that stops, prevents, or reduces the frequency, rate or extent of actin polymerization.
    GO:0018108    peptidyl-tyrosine phosphorylation    The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.
    GO:0043538    regulation of actin phosphorylation    Any process that modulates the frequency, rate or extent of the transfer of one or more phosphate groups to an actin molecule.
    GO:0042989    sequestering of actin monomers    The selective interaction of actin monomers with specific molecules that inhibit their polymerization by preventing their access to other monomers.
cellular component
    GO:0015629    actin cytoskeleton    The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.
    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:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005856    cytoskeleton    Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
    GO:0030175    filopodium    Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft.
    GO:0005925    focal adhesion    Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
    GO:0030016    myofibril    The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism.
    GO:0048471    perinuclear region of cytoplasm    Cytoplasm situated near, or occurring around, the nucleus.
    GO:0032587    ruffle membrane    The portion of the plasma membrane surrounding a ruffle.
