GO: Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. [GOC:bf, GOC:ceb, ISBN:0198506732],NCI: Receptor Binding involves a temporary non-covalent, typically highly specific and high affinity, interaction through intermolecular physical forces of attraction and spatial complementarity with a diverse group of intrinsic membrane or cytoplasmic proteins that mediate the biological effects of secreted regulatory signaling molecules through modification of the activity of signal transduction pathways.
