Study of V2 vasopressin receptor hormone binding site using in silico methods.

ABSTRACT: The antidiuretic effect of arginine vasopressin (AVP) is mediated by the vasopressin V2 receptor. The docking study of AVP as a ligand to V2 receptor helps in identifying important amino acid residues that might be involved in AVP binding for predicting the lowest free energy state of the protein complex. Whereas previous researchers were not able to detect the exact site of the ligand-receptor binding, we designed the current study to identify the vasopressin V2 receptor hormone binding site using bioinformatic methods. The 3D structure of nonapeptide hormone vasopressin was extracted from Protein Data Bank. Since no suitable template resembling V2 receptor was found, an ab initio approach was chosen to model the protein receptor. Using protein docking methods such as Hex protein-protein
