Protein Kinase Inhibitors
- An enzyme is a protein or RNA that acts as a biological catalyst, increasing the rate at which a chemical reaction occurs.
The human body probably contains about 10,000 different enzymes.
- A Kinase is a special enzyme that catalyzes the phosphoryl transfer reaction from a phosphate donor to a receptor substrate.
- A PK (Protein Kinase) is a special kinase that catalyzes proteins by transferring phosphate groups from ATPs (Adenosine TriphosPhates) to them.
- There are about 550 types of Protein Kinases in our body and responsible for phosphorylating about one third of all proteins in our body.
- All Protein Kinases share a similar structure which has two distinct subdomains, a smaller N-terminal lobe (N-lobe) and a larger C-terminal lobe (C-lobe), linked by a short Hinge loop.
- A Protein Kinase Activation is the phosphorylation process of a protein kinase that changes its state from inactive to active and becomes ready to phosphorylates other proteins.
- A Protein Kinase Activation Cascade is a sequence of Protein Kinase Activations where an activated protein kinase activates another protein kinase which in turn activates another protein kinase, and so on.
- A Protein Kinase Inhibitor is a small molecule that docks into a pocket of a protein kinase to inhibits, or blocks, its phosphorylation, or catalysis, function.
