a feedback inhibitor of growth factor receptor signaling. Belongs to the sprouty family. May function as an antagonist of fibroblast growth factor (FGF) pathways and may negatively modulate respiratory organogenesis. Associated with microtubules in unstimulated cells but is translocated to the membrane ruffles in cells stimulated with EGF (epidermal growth factor). Note: This description may include information from UniProtKB.
