molecular function |
| GO:0051117 | | ATPase binding | | Interacting selectively and non-covalently with an ATPase, any enzyme that catalyzes the hydrolysis of ATP. |
| GO:0044548 | | S100 protein binding | | Interacting selectively and non-covalently with a S100 protein. S100 is a small calcium and zinc binding protein produced in astrocytes that is implicated in Alzheimer's disease, Down Syndrome and ALS. |
| 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:0042802 | | identical protein binding | | Interacting selectively and non-covalently with an identical protein or proteins. |
| 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. |
biological process |
| GO:0035556 | | intracellular signal transduction | | The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. |
| GO:0000122 | | negative regulation of transcription from RNA polymerase II promoter | | Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| GO:1901387 | | positive regulation of voltage-gated calcium channel activity | | Any process that activates or increases the frequency, rate or extent of voltage-gated calcium channel activity. |
| GO:0008016 | | regulation of heart contraction | | Any process that modulates the frequency, rate or extent of heart contraction. Heart contraction is the process in which the heart decreases in volume in a characteristic way to propel blood through the body. |
| GO:0021762 | | substantia nigra development | | The progression of the substantia nigra over time from its initial formation until its mature state. The substantia nigra is the layer of gray substance that separates the posterior parts of the cerebral peduncles (tegmentum mesencephali) from the anterior parts; it normally includes a posterior compact part with many pigmented cells (pars compacta) and an anterior reticular part whose cells contain little pigment (pars reticularis). |
cellular component |
| GO:0031672 | | A band | | The dark-staining region of a sarcomere, in which myosin thick filaments are present; the center is traversed by the paler H zone, which in turn contains the M line. |
| GO:0031674 | | I band | | A region of a sarcomere that appears as a light band on each side of the Z disc, comprising a region of the sarcomere where thin (actin) filaments are not overlapped by thick (myosin) filaments; contains actin, troponin, and tropomyosin; each sarcomere includes half of an I band at each end. |
| GO:0031430 | | M band | | The midline of aligned thick filaments in a sarcomere; location of specific proteins that link thick filaments. Depending on muscle type the M band consists of different numbers of M lines. |
| GO:0030018 | | Z disc | | Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0043005 | | neuron projection | | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
| GO:0043234 | | protein complex | | A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical. |
| GO:0016529 | | sarcoplasmic reticulum | | A fine reticular network of membrane-limited elements that pervades the sarcoplasm of a muscle cell; continuous over large portions of the cell and with the nuclear envelope; that part of the endoplasmic reticulum specialized for calcium release, uptake and storage. |
