Summary: Predicted to enable guanyl-nucleotide exchange factor activity. Involved in regulation of Rap protein signal transduction. Predicted to be active in plasma membrane. Is expressed in adult head; midline glial cell; and midline primordium. Human ortholog(s) of this gene implicated in autistic disorder and nicotine dependence. Orthologous to several human genes including RAPGEF4 (Rap guanine nucleotide exchange factor 4). [provided by Alliance of Genome Resources, Dec 2024]
