Is an ortholog of human RGS9 (regulator of G protein signaling 9). Exhibits GTPase activator activity. Is involved in several processes, including G protein-coupled receptor signaling pathway\; modulation of chemical synaptic transmission\; and negative regulation of locomotion. Localizes to the cytoplasm\; neuron projection\; and plasma membrane. Is expressed in the nervous system\; the pharyngeal muscle cell\; and the vulval muscle. Human ortholog(s) of this gene are implicated in bradyopsia.
