Asymmetric Unit(hide GO term definitions)
Chain A,B,C,D   (TNNC1_HUMAN | P63316)
molecular function
    GO:0051015    actin filament binding    Interacting selectively and non-covalently with an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0048306    calcium-dependent 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), in the presence of calcium.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    GO:0031013    troponin I binding    Interacting selectively and non-covalently with troponin I, the inhibitory subunit of the troponin complex.
    GO:0031014    troponin T binding    Interacting selectively and non-covalently with troponin T, the tropomyosin-binding subunit of the troponin complex.
biological process
    GO:0060048    cardiac muscle contraction    Muscle contraction of cardiac muscle tissue.
    GO:0002086    diaphragm contraction    A process in which force is generated within involuntary skeletal muscle tissue, resulting in a change in muscle geometry. This process occurs in the diaphragm. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The diaphragm is a striated muscle that is necessary for the process of respiratory gaseous exchange.
    GO:0030049    muscle filament sliding    The sliding of actin thin filaments and myosin thick filaments past each other in muscle contraction. This involves a process of interaction of myosin located on a thick filament with actin located on a thin filament. During this process ATP is split and forces are generated.
    GO:0043462    regulation of ATPase activity    Any process that modulates the rate of ATP hydrolysis by an ATPase.
    GO:0006937    regulation of muscle contraction    Any process that modulates the frequency, rate or extent of muscle contraction.
    GO:0032972    regulation of muscle filament sliding speed    Any process that modulates the velocity of muscle filament sliding.
    GO:0010038    response to metal ion    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 a metal ion stimulus.
    GO:0014883    transition between fast and slow fiber    The process of conversion of fast-contracting muscle fibers to a slower character. This may involve slowing of contractile rate, slow myosin gene induction, increase in oxidative metabolic properties, altered electrophysiology and altered innervation. This process also regulates skeletal muscle adapatation.
    GO:0055010    ventricular cardiac muscle tissue morphogenesis    The process in which the anatomical structures of cardiac ventricle muscle is generated and organized.
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:0043292    contractile fiber    Fibers, composed of actin, myosin, and associated proteins, found in cells of smooth or striated muscle.
    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:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005861    troponin complex    A complex of accessory proteins (typically troponin T, troponin I and troponin C) found associated with actin in muscle thin filaments; involved in calcium regulation of muscle contraction.
