Molecular Characterization: GCGR(Ala26-Lys136) hFc(Glu99-Ala330)Molecular weight: The protein has a predicted molecular mass of 39.2 kDa after removal of the signal peptide. The apparent molecular mass of GCGR-hFc is approximately 55-70 kDa due to glycosylation.Description: Recombinant human GCGR protein with C-terminal human Fc tagThe protein encoded by this gene is a glucagon receptor that is important in controlling blood glucose levels. Defects in this gene are a cause of non-insulin-dependent diabetes mellitus (NIDDM).
