Predicted to enable GTPase activator activity; metal ion binding activity; and phospholipid binding 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. Orthologous to several human genes including RASA4 (RAS p21 protein activator 4). [provided by Alliance of Genome Resources, Apr 2022]
