AutoDock can be used when the structure of the ligand and the protein are both known, but the location of the binding site is unknown. This is often referred to as “blind docking.” This is a challenge because you need to set up the dockings to search the entire surface of the protein (or other macromolecule) of interest. This can be achieved using AutoGrid to create very large grid maps, with the maximum number of points in each dimension, and if necessary, creating sets of adjacent grid map volumes that cover the macromolecule. The third-party tool BDT can be used to set up such sets of grid maps.
You can also use AutoLigand to predict the probable binding sites on a protein surface, and limit docking simulations to those locations.
Several laboratories have used AutoDock to perform blind docking, for example:
