molecular function |
| GO:0017112 | | Rab guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rab 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: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:0019208 | | phosphatase regulator activity | | Modulates the activity of a phosphatase, an enzyme which catalyzes of the removal of a phosphate group from a substrate molecule. |
| GO:0001691 | | pseudophosphatase activity | | Maintains the phosphorylation state of certain molecules by associating with them and preventing them from associating with active phosphatases, and thus inhibiting the enzyme activity without interacting with the enzyme. Often pertains to proteins belonging to dual-specificity phosphatase family but lacking critical active site residues. |
biological process |
| GO:0043086 | | negative regulation of catalytic activity | | Any process that stops or reduces the activity of an enzyme. |
| GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| GO:0043087 | | regulation of GTPase activity | | Any process that modulates the rate of GTP hydrolysis by a GTPase. |
| GO:0001558 | | regulation of cell growth | | Any process that modulates the frequency, rate, extent or direction of cell growth. |
| GO:0007283 | | spermatogenesis | | The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis. |
cellular component |
| GO:0005575 | | cellular_component | | The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
| 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. |
