Predicted to enable cell adhesion molecule binding activity. Involved in hemopoiesis; homophilic cell adhesion via plasma membrane adhesion molecules; and nervous system development. Acts upstream of or within glomerulus morphogenesis; inter-male aggressive behavior; and nervous system development. Located in several cellular components, including axon; dendritic shaft; and extracellular region. Is integral component of membrane. Is expressed in central nervous system; dorsal root ganglion; glomerular tuft; and sensory organ. Human ortholog(s) of this gene implicated in autosomal dominant non-syndromic intellectual disability 4. Orthologous to human KIRREL3 (kirre like nephrin family adhesion molecule 3).
