Displays low GTPase activity and exists predominantly in the GTP-bound form (By similarity). Together with epac-1, may regulate acetylcholine release at the neuromuscular junctions probably downstream of G-protein gsa-1 and adenylate cyclase acy-1 (PubMed:22897658). Interacts with epac-1 (via C-terminus). Expressed specifically in neurons including the nerve ring, ventral and dorsal nerve cord motor neurons and tail ganglia. Viable and fertile. Resistant to paralysis induced by treatment with acetylcholinesterase inhibitor aldicarb (but not with acetylcholine agonist levamisole). Hypersensitivity to aldicarb treatment is partially reduced in an egl-30(js126), goa-1(n1134) or gsa-1(ce94) mutant background. Belongs to the small GTPase superfamily. Di-Ras family.
