Enables enzyme binding activity and vascular endothelial growth factor receptor binding activity. Involved in several processes, including negative regulation of cellular response to growth factor stimulus; negative regulation of protein phosphorylation; and regulation of Rac protein signal transduction. Predicted to be located in cell leading edge and cell-cell contact zone. Is expressed in dorsal root ganglion; spinal cord; spinal cord gray matter; and spinal cord white matter. Orthologous to human CADM4 (cell adhesion molecule 4). [provided by Alliance of Genome Resources, Apr 2022]
