Insulin receptor inactivated (left) and activated (right) after insulin binding
The insulin receptor (blue) is a transmembrane protein, that is activated by insulin (orange). Insulin binding induces structural changes within the receptor that finally leads  to the activation of the glucose transporter protein.

Structure of follicle-stimulating hormone (color) in complex with the entire ectodomain of its receptor (grey), 3D Gaussian surface model, white background
Activation of the GABA B receptor by baclofen. GABA B receptors  are G protein-coupled receptors.  Binding of  an agonist (baclofen, red) leads to a G-protein coupled C-AMP signaling pathway. Source: PDB entries 7eb2, 6r3q,.

3d computer illustration of an activated Ras  protein with GTP bound. Ras proteins are involved in transmitting signals within cells turning on genes involved in cell growth, differentiation and survival. Mutations in ras genes can lead to permanentl
Calmodulin, a crucial messenger protein
3d computer illustration of the activation process of a Ras protein. Inactive Ras protein (left) is activated by a GEF protein opening the binding site and allowing GDP to exit. Afterwards GTP can bind to RAS turning it into the active form (right).
Activation of the immune response to an antigene (green) through the complex between a T-cell receptor (dark blue), an MHC II-antigen (violet) and a CD4 protein (light blue). 3d rendering. Illustration
Activation of a Ras protein Inactive Ras protein (left) is activated by a GEF protein opening the binding site allowing GDP to exit. Then GTP can bind to RAS turning it into the active form. 3d render. Illustration
Dendritic cells present antigens (green) to lymphocytes through their membran bound MHC-molecules (violet). CD4 molecules (light blue) bind to other portions of the MHC, strengthening the interaction.
Cancer cells express PD-L1 (orange) proteins on their surface to trick the immune system. The interaction of PD-L1 with PD-1 of  T-cells leads to a down-regulation of T-cells. The antibody (yellow) blocks this interaction.
Calmodulin, inactive-calcium free (left), and activated  (right) conformations,
Calmodulin, a crucial messenger protein. Calmodulin has 4 Ca2+ binding sites.
