title: Getting it together: signal transduction in G-protein coupled receptors by association of receptor domains.
abstract: The mechanism of signal transduction by G-protein coupled receptors is unknown. Here, we propose that these receptors signal in a way that is qualitatively similar to that seen in the chemokine and endocrine hormone receptor families; the signal occurs when two domains of the receptor are brought together, although this is not the only requirement for signaling.
