CC   -!- FUNCTION: Involved in exocytosis. Maybe by regulating the binding and
CC       fusion of secretory vesicles with the cell surface. The GTP-bound form
CC       of SEC4 may interact with an effector, thereby stimulating its activity
CC       and leading to exocytotic fusion. SEC4 may be an upstream activator of
CC       the 19.5S SEC8/SEC15 particle. SEC4 probably interacts directly with
CC       SEC8; it could serve as the attachment site for the SEC8/SEC15 particle
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle membrane
CC       {ECO:0000250}; Lipid-anchor {ECO:0000250}; Cytoplasmic side
CC       {ECO:0000250}. Cell membrane {ECO:0000250}; Lipid-anchor {ECO:0000250};
CC       Cytoplasmic side {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the small GTPase superfamily. Rab family.
CC       {ECO:0000305}.
