Membrane vs. Extracellular Soluble Receptors

CELLS-VYBA4F

Substance J binds to the substance J receptor that is embedded in cell membranes. However, when the physiology of the organism dictates that there is too much signaling by substance J, a gene is turned on for another receptor that can also recognize substance J.

This receptor diffuses around in the extracellular space and "soaks" up the substance J so that it cannot activate its cellular receptor.

This latter receptor type is called a

A

orphan receptor.

B

G-protein coupled receptor.

C

nicotine receptor.

D

nomad receptor.

E

decoy receptor.
