Predicted to enable chemorepellent activity and semaphorin receptor binding activity. Predicted to be involved in several processes, including generation of neurons; neural crest cell migration; and semaphorin-plexin signaling pathway. Predicted to be located in plasma membrane and synapse. Predicted to be active in extracellular space. Predicted to be integral component of plasma membrane. Orthologous to human SEMA4B (semaphorin 4B). [provided by Alliance of Genome Resources, Apr 2022]
