molecular function |
| GO:0003779 | | actin binding | | Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments. |
| GO:0019855 | | calcium channel inhibitor activity | | Stops, prevents, or reduces the activity of a calcium channel. |
| 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:0019904 | | protein domain specific binding | | Interacting selectively and non-covalently with a specific domain of a protein. |
| GO:0019901 | | protein kinase binding | | Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate. |
| GO:0030172 | | troponin C binding | | Interacting selectively and non-covalently with troponin C, the calcium-binding subunit of the troponin complex. |

biological process |
| GO:0060048 | | cardiac muscle contraction | | Muscle contraction of cardiac muscle tissue. |
| GO:0006874 | | cellular calcium ion homeostasis | | Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell. |
| GO:0060047 | | heart contraction | | The multicellular organismal process in which the heart decreases in volume in a characteristic way to propel blood through the body. |
| GO:0007507 | | heart development | | The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood. |
| 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:0032780 | | negative regulation of ATPase activity | | Any process that stops or reduces the rate of ATP hydrolysis by an ATPase. |
| GO:1903779 | | regulation of cardiac conduction | | Any process that modulates the frequency, rate or extent of cardiac conduction. |
| GO:0006937 | | regulation of muscle contraction | | Any process that modulates the frequency, rate or extent of muscle contraction. |
| GO:0006940 | | regulation of smooth muscle contraction | | Any process that modulates the frequency, rate or extent of smooth muscle contraction. |
| GO:0001980 | | regulation of systemic arterial blood pressure by ischemic conditions | | The process that modulates blood pressure by the detection of carbon dioxide levels in the brain stem. Increased levels activate the sympathetic vasoconstrictor mechanism increasing the force with which blood flows through the circulatory system. |
| GO:0003009 | | skeletal muscle contraction | | A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. 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. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control. |
| GO:0006941 | | striated muscle contraction | | A process in which force is generated within striated muscle tissue, resulting in the shortening of the muscle. 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. Striated muscle is a type of muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope. |
| GO:0001570 | | vasculogenesis | | The differentiation of endothelial cells from progenitor cells during blood vessel development, and the de novo formation of blood vessels and tubes. |
| 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:0043292 | | contractile fiber | | Fibers, composed of actin, myosin, and associated proteins, found in cells of smooth or striated muscle. |
| 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: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:0030017 | | sarcomere | | The repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs. |
| 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. |
