背景（Background）
IGFBP5 stands for Insulin-like Growth Factor Binding Protein 5. It is a protein that belongs to the insulin-like growth factor binding protein (IGFBP) family. IGFBP5 plays a crucial role in regulating the activity and distribution of insulin-like growth factors (IGFs) in the body. Enables insulin-like growth factor I binding activity.
