CC -!- FUNCTION: GDP-GTP exchange factor (GEF) for the small GTPase BUD1/RSR1.
CC Regulates the activity of BUD1 together with BUD2 which is a GTPase-
CC activating protein (GAP) of BUD1. Required to produce both the axial
CC and bipolar patterns of bud site selection. Determines the orientation
CC of division axis. Overexpression can suppress mutations in PRP20 which
CC is the GEF for GSP1. May be a cytoplasmic GEF for GSP1. Might also act
CC on the Ras-like protein CDC42. Appears to bind to Ras proteins but not
CC to activate them. {ECO:0000269|PubMed:11378394,
CC ECO:0000269|PubMed:11589573, ECO:0000269|PubMed:8234337}.
CC -!- SUBUNIT: Interacts with AXL2, BEM1, GSP1 and in haploid cells with
CC AXL1. {ECO:0000269|PubMed:11313501, ECO:0000269|PubMed:11589573,
CC ECO:0000269|PubMed:12176366}.
CC -!- INTERACTION:
CC P25300; P38928: AXL2; NbExp=2; IntAct=EBI-3853, EBI-3397;
CC P25300; P32835: GSP1; NbExp=2; IntAct=EBI-3853, EBI-7926;
CC -!- SUBCELLULAR LOCATION: Bud neck. Cytoplasm, cell cortex. Note=In haploid
CC cells, forms double rings that encircle the mother-bud neck and split
CC upon cytokinesis, each progeny cell inheriting BUD5 at the axial
CC division remnant. In diploid cells, localizes to the poles of the cell.
CC -!- MISCELLANEOUS: Present with 2110 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
