molecular function |
| GO:0001965 | | G-protein alpha-subunit binding | | Interacting selectively and non-covalently with a G-protein alpha subunit. The alpha subunit binds a guanine nucleotide. |
| GO:0005096 | | GTPase activator activity | | Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP. |
biological process |
| GO:0045744 | | negative regulation of G-protein coupled receptor protein signaling pathway | | Any process that stops, prevents, or reduces the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity. |
| GO:0009968 | | negative regulation of signal transduction | | Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction. |
| GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
cellular component |
| 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:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| 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:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| 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. |
