Whooping cough is the result of toxins catalyzing a cysteine residue's ADP‐ribosylation.
Both pseudohypoparathyroidism and McCune-Albright Syndrome are caused by mutations to these molecules. Calmodulin can reverse the inhibition on the RGS protein, which regulate these molecules, caused by PIP3. Whooping cough is the result of toxins catalyzing a cysteine residue's ADP‐ribosylation. These molecules are often structural (*) heterotrimers and thus have an alpha subunit that separates from the beta-gamma subunit upon activation. Richard Axel and Linda Buck won the 2004 Nobel Prize in Physiology for showing that olfactory receptors activate these proteins. Ras proteins are a type of these proteins, which control the production of second messengers such as cyclic AMP. Cholera toxins target, for 10 points, which group of signaling proteins named for their ability to bind to guanosine triphosphate?

G Proteins [accept guanine nucleotide-binding proteins before "guanosine"; or GTP-binding proteins before "guanonsine"]
