These resources explore proteins by their different function, with examples of how they give structure to living things, carry messages and molecules around our bodies, support the immune system, catalyse chemical reactions, and their use in industry and medicine:
Structure and movement How proteins give structure to organisms and help them move. The examples used are collagen and microtubules.
Transport How proteins, such as haemoglobin, carry substances from place to place. The role of membrane bound proteins such as membrane receptors, channels and pumps is described. There is also a focus on the role of the cystic fibrosis transmembrane conductance regulator (CFTR) which regulates the movement of chloride ions.
Defence and survival How proteins such as immunoglobulin keep humans alive and well, and what happens when protein folding goes wrong.
Signalling How proteins are involved in cell signalling and communication, with a focus on insulin, hormones, kinases and pheromones.
Catalysis How, as enzymes, proteins catalyse reactions. The example of ATP synthase is used.
