Predicted to enable GTPase activator activity. Predicted to be involved in several processes, including cellular response to calcium ion; negative regulation of Ras protein signal transduction; and regulation of GTPase activity. Predicted to be located in cytosol. Predicted to colocalize with plasma membrane. Is expressed in trigeminal ganglion. Orthologous to several human genes including RASA4 (RAS p21 protein activator 4). [provided by Alliance of Genome Resources, Apr 2022]
