Predicted to enable growth factor activity and nerve growth factor receptor binding activity. Predicted to be involved in several processes, including cell surface receptor signaling pathway; ganglion mother cell fate determination; and nervous system development. Predicted to act upstream of or within negative regulation of cell death; nervous system development; and taste bud development. Predicted to be located in extracellular region. Predicted to be active in several cellular components, including axon; dendrite; and synaptic vesicle. Orthologous to human NTF4 (neurotrophin 4). [provided by Alliance of Genome Resources, Apr 2022]
