Enables growth factor binding activity and vascular endothelial growth factor-activated receptor activity. Involved in positive regulation of cell growth and vascular endothelial growth factor receptor signaling pathway. Predicted to be located in cytosol; nucleoplasm; and plasma membrane. Predicted to be part of receptor complex. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in hereditary lymphedema IA. Orthologous to human FLT4 (fms related receptor tyrosine kinase 4). [provided by Alliance of Genome Resources, Apr 2022]
