What is the most common mechanism for deactivation of the hormone receptor in G-protein-associated signaling?
A) Degradation of hormone
B) Degradation of receptor
C) GTP hydrolysis
D) Phosphorylation of receptor
E) Receptor internalization

Question

Quizplus · Accepted Answer

Phosphorylation of the receptor is the most common mechanism for deactivation of the hormone receptor in G-protein-associated signaling. This phosphorylation leads to the recruitment of arrestin proteins and ultimately receptor internalization and desensitization.
