Chain A   (CDC24_YEAST | P11433)
molecular function
    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: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: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).
biological process
    GO:0000282    cellular bud site selection    The specification of the site where a daughter cell will form, in organisms that reproduce by budding. An example of this process is found in Saccharomyces cerevisiae.
    GO:0035556    intracellular signal transduction    The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0072697    protein localization to cell cortex    A process in which a protein is transported to, or maintained in, the cell cortex.
    GO:0035023    regulation of Rho protein signal transduction    Any process that modulates the frequency, rate or extent of Rho protein signal transduction.
    GO:0007096    regulation of exit from mitosis    Any process involved in the progression from anaphase/telophase to G1 that is associated with a conversion from high to low mitotic CDK activity.
    GO:0031106    septin ring organization    Control of the formation, spatial distribution, and breakdown of the septin ring.
    GO:0007264    small GTPase mediated signal transduction    Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.
cellular component
    GO:0005935    cellular bud neck    The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding.
    GO:0005934    cellular bud tip    The end of a cellular bud distal to the site of attachment to the mother cell.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0000131    incipient cellular bud site    The portion of the budding yeast plasma membrane where a daughter cell will emerge. The yeast marks this spot with bud-site selection proteins before bud emergence occurs. Actin is polarized to this spot just prior to and during bud emergence.
    GO:0043332    mating projection tip    The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.
    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.
