Enriched GO terms in this set:

GO:0003674 (molecular_function)
"Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions."

    GO:0030234 (enzyme regulator activity)
    "Modulates the activity of an enzyme."

        GO:0030695 (GTPase regulator activity) [p = 0.002   (3/33: ROM1; TUS1; IRA2)]
        "Modulates the rate of GTP hydrolysis by a GTPase."

            GO:0005083 (small GTPase regulator activity) [p = 0.001   (3/25: ROM1; TUS1; IRA2)]
            "Modulates the rate of GTP hydrolysis by a small monomeric GTPase."

                GO:0005088 (Ras guanyl-nucleotide exchange factor activity) [p = 0.006   (2/5: ROM1; TUS1)]
                "Stimulates the exchange of guanyl nucleotides by a GTPase of the Ras superfamily. 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:0005089 (Rho guanyl-nucleotide exchange factor activity) [p = 0.002   (2/3: ROM1; TUS1)]
                    "Stimulates the exchange of guanyl nucleotides by 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:0008150 (biological_process)
"Those processes specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end."

    GO:0009987 (cellular process)
    "Processes that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level."

        GO:0007154 (cell communication) [p = 0.002   (4/119: ROM1; TUS1; IRA2; PDE2)]
        "Any process that mediates interactions between a cell and its surroundings. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment."

            GO:0007165 (signal transduction) [p = 0.002   (4/114: ROM1; TUS1; IRA2; PDE2)]
            "The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell."
