molecular function |
| GO:0005524 | | ATP binding | | Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| GO:0005089 | | Rho guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase. |
| GO:0030506 | | ankyrin binding | | Interacting selectively and non-covalently with ankyrin, a 200 kDa cytoskeletal protein that attaches other cytoskeletal proteins to integral membrane proteins. |
| 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:0005085 | | guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase. |
| GO:0016301 | | kinase activity | | Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| 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:0004672 | | protein kinase activity | | Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP. |
| GO:0004674 | | protein serine/threonine kinase activity | | Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. |
| GO:0008307 | | structural constituent of muscle | | The action of a molecule that contributes to the structural integrity of a muscle fiber. |
| GO:0031432 | | titin binding | | Interacting selectively and non-covalently with titin, any of a family of giant proteins found in striated and smooth muscle. In striated muscle, single titin molecules span half the sarcomere, with their N- and C-termini in the Z-disc and M-line, respectively. |
| GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
biological process |
| GO:0030154 | | cell differentiation | | The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
| GO:0007275 | | multicellular organism development | | The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult). |
| GO:0016310 | | phosphorylation | | The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide. |
| GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| GO:0043065 | | positive regulation of apoptotic process | | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
| GO:0098779 | | positive regulation of macromitophagy in response to mitochondrial depolarization | | The macromitophagy process that is triggered by a detection of the loss of mitochondrial membrane potential. |
| GO:0036309 | | protein localization to M-band | | Any process in which a protein is transported to, and/or maintained in, the M band. The M band is the midline of aligned thick filaments in a sarcomere. |
| GO:0006468 | | protein phosphorylation | | The process of introducing a phosphate group on to a protein. |
| GO:0035023 | | regulation of Rho protein signal transduction | | Any process that modulates the frequency, rate or extent of Rho protein signal transduction. |
| GO:0051056 | | regulation of small GTPase mediated signal transduction | | Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction. |
| GO:0045214 | | sarcomere organization | | The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is 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. |
cellular component |
| 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: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. |
