Enables platelet-derived growth factor receptor binding activity. Involved in positive regulation of cold-induced thermogenesis. Acts upstream of or within several processes, including cellular response to amino acid stimulus; platelet-derived growth factor receptor signaling pathway; and regulation of protein phosphorylation. Located in extracellular region. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Orthologous to human PDGFC (platelet derived growth factor C). [provided by Alliance of Genome Resources, Apr 2022]
