SAR1, p195, HUMORFA1, Ras GTPase-activating-like protein IQGAP1, IQGAP1, KIAA51
Binds to activated CDC42 but does not stimulate its GTPase activity. It associates with calmodulin. Could serve as an assembly scaffold for the organization of a multimolecular complex that would interface incoming signals to the reorganization of the ac
