Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (SPTN1_CHICK | P07751)
molecular function
    GO:0003779    actin binding    Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments.
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0005516    calmodulin binding    Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
biological process
    GO:0051693    actin filament capping    The binding of a protein or protein complex to the end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits.
cellular component
    GO:0005938    cell cortex    The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
    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.
