Predicted to be involved in negative regulation of axon extension and positive regulation of peptidyl-lysine acetylation. Predicted to act upstream of or within nervous system development. Predicted to be located in axon; dendrite; and perikaryon. Is expressed in axial mesoderm and notochord. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder. Orthologous to human DIP2B (disco interacting protein 2 homolog B).
