Igfbp3 Gene Summary [Mouse]
Enables fibronectin binding activity and insulin-like growth factor binding activity. Involved in osteoblast differentiation. 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; brain; early embryo; gonad; and limb. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease; Turner syndrome; diabetes mellitus (multiple); prostate cancer; and transitional cell carcinoma. Orthologous to human IGFBP3 (insulin like growth factor binding protein 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Igfbp3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
