Predicted to enable identical protein binding activity. Predicted to be involved in axon extension involved in axon guidance; heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; and retinal ganglion cell axon guidance. Predicted to act upstream of or within motor neuron axon guidance. Predicted to be located in several cellular components, including external side of plasma membrane; immunological synapse; and neuronal cell body. Predicted to be integral component of plasma membrane. Predicted to be active in plasma membrane. Orthologous to human ALCAM (activated leukocyte cell adhesion molecule).
