|cAMP. Picture from Wikipedia.|
So, in my WTF-moment of the day, I was reading about various RNA, then nucleotides, etc, and got to cAMP. This, and I know that from WikiPathways too, can act as a secondary signalling compound: membrane receptor passes the signal on to cAMP. But then? I mean, one single molecule. Supposed to give a variety of signals. How?? How can it be selective? How is the hormone-specific signal not lost when passing the cytoplasma?? Or is it just a general "ALERT ALERT, SOMETHING OUTSIDE HAPPENED"?
