Predicted to enable GTPase activity and molecular adaptor activity. Predicted to be involved in cellular protein localization; cytoskeleton-dependent cytokinesis; and positive regulation of non-motile cilium assembly. Predicted to act upstream of or within cell division. Part of septin complex. Is expressed in several structures, including branchial arch; embryo mesenchyme; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in brachial plexus neuritis. Orthologous to human SEPTIN9 (septin 9). [provided by Alliance of Genome Resources, Apr 2022]
