The <scene name='10/1038815/Overview/3'>binding site</scene> of GIP with the GIP receptor (GIPR) is where the N-term of GIP binds with the transmembrane domain of the GIP receptor. This first interaction formed with GIPR and the N-term of GIP is a hydrogen bond between TYR1 and GLU224.

The <scene name='10/1038815/Overview/3'>binding site</scene> of GIP with the GIP receptor (GIPR) is where the N-term of GIP binds with the transmembrane domain of the GIP receptor. This first interaction formed with GIPR and the N-term of GIP is a hydrogen bond between Tyrosine 1 (Y1) and Glutamine 224 (Q224) to activate the G-protein to start sending signals to the cell.

The <scene name='10/1038815/Active_site/3'>residues</scene> within the active site are forming hydrogen bonds with each other and activating the G-protein to start signaling.
+
Many other <scene name='10/1038815/Active_site/3'>residues</scene> within the binding site are forming hydrogen bonds and hydrophobic interactions between the ligand and the receptor. The N-term binds more strongly than the C-term and there are many different residues contributing to this, including, Tyrosine 1 (Y1) and Tryptophan (W296) are forming aromatic interactions. Serine 8 (S8) and Asparagine 290 (N290) are forming two hydrogen bonds with each other. Aspartate 9 (D9) is forming another hydrogen bond with Arginine 370 (R370).
