Keyword - Signal transduction inhibitor (KW-0734)


Protein which inhibits signal transduction, the process by which extracellular signals induce intracellular responses. Usually a hormone or neurotransmitter binds to a cell surface receptor which is coupled to a second messenger system, such as that involving cAMP, or to an ion channel. The final downstream consequence of signal transduction is a change in the cell's function, such as a modification in glucose uptake or in cell division. Such a change may be the result of an activation or an inhibition event.
