| GO:0007265 | Ras protein signal transduction | biological_process | A series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state. [GOC:bf] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
| GO:0043547 | positive regulation of GTPase activity | biological_process | Any process that activates or increases the activity of a GTPase. [GOC:jl, GOC:mah] |
| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| GO:0050790 | regulation of catalytic activity | biological_process | Any process that modulates the activity of an enzyme. [GOC:ai, GOC:ebc, GOC:vw] |
| GO:0005085 | guanyl-nucleotide exchange factor activity | molecular_function | Stimulates the exchange of GDP to GTP on a signaling GTPase, changing its conformation to its active form. Guanine nucleotide exchange factors (GEFs) act by stimulating the release of guanosine diphosphate (GDP) to allow binding of guanosine triphosphate (GTP), which is more abundant in the cell under normal cellular physiological conditions.

| GO:0007264 | small GTPase mediated signal transduction | biological_process | Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals. [GOC:mah] |
