SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus

basic FUNCTION	playing a role in intracellular signaling and actin dynamics at the Golgi apparatus (Ishikawa 2005)
	functions as a bona fide guanine nucleotide exchange factor (GEF) that facilitates activation of the small GTPases RAC1, CDC42, and RHOA
	aggregation-prone member of the Dbl family GEFs
