IGFBP3 Proteins

Protein Information

IGFBP3 is a gene that belongs to the insulin-like growth factor binding protein (IGFBP) family. The gene encodes a protein that contains both an IGFBP domain and a thyroglobulin type-I domain. This protein is known to form a ternary complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor (IGF) I or II. The complex circulates in the plasma and prolongs the half-life of IGFs while also altering their interaction with cell surface receptors. Various isoforms of the gene have been identified through alternate transcriptional splice variants. Diseases associated with IGFBP3 include Insulin-Like Growth Factor I and Acid-Labile Subunit Deficiency.
