the component of a cell or organism that interacts with a drug and initiates the chain of events leading to the drug's observed effects	RECEPTOR
• Their ligands are presently unknown • May prove useful targets for the development of new drugs.	ORPHAN RECEPTORS
• MEDIATE the actions of endogenous chemical signals such as neurotransmitters, autacoids and hormones.	REGULATORY PROTEINS
• also identified as drug receptors • may be inhibited or activated by binding a drug • Ex: dihydrofolate reductase for methotrexate	ENZYMES
