Caenorhabditis elegans Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in several processes, including cellular component organization; modulation of chemical synaptic transmission; and positive regulation of protein localization to synapse. Located in axon; cytoplasm; and muscle cell projection. Expressed in several structures, including egg-laying apparatus; hermaphrodite gonad; lumbar ganglion; neurons; and tail hypodermis. Used to study epilepsy. Human ortholog(s) of this gene implicated in artery disease (multiple); autosomal dominant intellectual developmental disorder 44; and cerebral infarction. Is an ortholog of human KALRN (kalirin RhoGEF kinase) and TRIO (trio Rho guanine nucleotide exchange factor).
