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 GIPR. The 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.

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). These hydrogen bonds lead to the activation of cell signaling and when this binding is somehow disrupted, that is what causes different diseases like diabetes.
