Glycine 172-179 gastric inhibitory polypeptide Homo sapiens 156-159 12525257-10 2003 These data indicate that substitution of the penultimate Ala2 in GIP by Gly or Ser confers resistance to plasma DPP IV degradation, resulting in enhanced biological activity, therefore raising the possibility of their use in the treatment of type 2 diabetes. Glycine 72-75 gastric inhibitory polypeptide Homo sapiens 65-68
