Due to the clinical importance of the Dopamine D2-receptor (D2R) in several brain dysfunctions, the utilization of in silico models for drug development is a growing field of investigation. We provided a transparent and reproducible pipeline for creating a valid D2R model for small molecular docking studies. Furthermore, we suggested a binding pocket for the endogenous ligand of D2R, which was attained upon careful consideration of the available experimental data. Molecular docking studies with Dopamine, Quinpirole and Raclopride allowed also a better understanding of the binding pocket characteristics.
