To identify structural characteristics of IGF-binding proteins that might define their physiological roles, we determined the complete primary structure of a novel human IGF-binding protein (IGFBP-2) from a cloned cDNA. The cDNA encodes a 328 amino acid IGF-binding protein precursor which contains a 39-residue signal peptide. The mature 289 amino acid IGFBP-2 has a predicted Mr of 31,325. Chinese hamster ovary (CHO) cells stably transformed with the IGFBP-2 cDNA secreted a 36 kd protein which bound, with different affinities, IGFII and IGFI, but did not bind insulin. The predicted protein sequence of this IGF-binding protein shares extensive amino acid homology (greater than 85%) with the IGF-binding protein secreted by rat BRL-3A cells, but less than 40% homology with human IGFBP-1. Therefore IGFBP-2, and not IGFBP-1 as previously suggested, represents the human homologue of the rat BRL-BP (alpha IGFBP-2). Moreover, from alignment of the predicted protein sequences of IGFBP-1 and IGFBP-2, extensive conservation of the distribution of cysteine residues is observed. Although the overall amino acid homology shared by these proteins is not high, we suggest that they represent a family of structurally related human IGFBPs. Southern blot analysis of human DNA demonstrates that IGFBP-2 is encoded by a single-copy gene, different from that of IGFBP-1."xsd:string
