title: Molecular expression of the negative growth factor murine beta-galactoside binding protein (mGBP).
abstract: Characterisation of the negative growth factor mGBP at molecular and biological levels indicates that the protein has no lectin nature and suggests instead a participation in the cytokine network. The protein is shown to be expressed as a monomer in two forms, one of which is non-covalently linked to a glycan complex. This confers greater efficiency to the inhibitor and may favour a paracrine role. The two monomeric forms may oxidise into tetramers which retain biological activity, but lack ability to link to specific saccharide residues.
