Corticotropin-releasing factor-binding protein is a glycoprotein.
Human corticotropin-releasing factor-binding protein (hCRF-BP), a 38,000 dalton protein, specifically binds hCRF in plasma. CRF-BP-CRF complex adsorbed to concanavalin-A-Sepharose and its Mr decreased after treatment with endoglycosidase H or glycopeptidase A. The binding of CRF-BP to CRF decreased after treatment with endoglycosidase H. These results indicate that the CRF-BP is a glycoprotein that contains asparagine N-linked-type oligosaccharides, and such oligosaccharide chains are important for CRF-BP binding.
