Enables GTPase activator activity. Acts upstream of or within negative regulation of Rho protein signal transduction; negative regulation of systemic arterial blood pressure; and negative regulation of vascular associated smooth muscle contraction. Orthologous to human ARHGAP42 (Rho GTPase activating protein 42). [provided by Alliance of Genome Resources, Apr 2022]
