For insulin binding, it is generally more common for only one or two insulin molecules to bind to the receptor due to the occurrence of negative [http://en.wikipedia.org/wiki/Ligand_(biochemistry)#Receptor.2Fligand_binding_affinity affinity] at the binding site. The location of the second two binding sites are on the back side of the Beta subunits and lack favorable surface area. The binding of insulin to the binding sites 1 and 1', as well as one insulin to either binding site 2 or 2', is required for the activation of the insulin receptor and the change in conformation to the active T state. <ref> DOI 10.7554/eLife.48630 </ref>.

Although interactions at all four binding sites are highly hydrophobic, ligand binding interactions are different at <scene name='83/832953/Sites_1_and_1_prime_location/12'>sites 1 and 1'</scene> and <scene name='83/832953/Sites_2_and_2_prime_location/9'>sites 2 and 2'</scene> (Figure 4). Sites 1 and 1' have two disulfide bond linkages, along with HIS B5 from insulin interacting with <scene name='83/832953/Sites_1_and_1_prime_location/14'>PRO495, PHE497, ARG498</scene> residues from the FnIII-1 domain.
