Igfbp4 - insulin-like growth factor binding protein 4

Enables insulin-like growth factor binding activity. Acts upstream of or within several processes, including positive regulation of signal transduction; regulation of glucose metabolic process; and type B pancreatic cell proliferation. Located in extracellular space. Is expressed in several structures, including alimentary system; early embryo; female reproductive system; limb; and lung. Orthologous to human IGFBP4 (insulin like growth factor binding protein 4). [provided by Alliance of Genome Resources, Apr 2022]
