Enables several functions, including GTPase activator activity; platelet-derived growth factor receptor binding activity; and protein kinase binding activity. Involved in several processes, including activation of GTPase activity; cellular response to growth factor stimulus; and positive regulation of glucose import. Located in cytosol; nuclear membrane; and plasma membrane. Human ortholog(s) of this gene implicated in arteriovenous malformation and basal cell carcinoma. Orthologous to human RASA1 (RAS p21 protein activator 1). [provided by Alliance of Genome Resources, Apr 2022]
