There are many mutant of the S49 cell line that have a deficient adenylyl
cyclase system. I don't have any references handy (they're all home) but
I remember S49 cyc-, h21 and unc-.

I remember that S49 cyc- lacks Gs and therefore cannot activate the cyclase.
The other cell lines have similar mutations. Unfortunately, I don't think any
of them lack the adenylate cyclase or the PKA. I know that P.A. Insel and C.C.
Malbon worked with them a few years ago.

Hope this helps. It would have been better if I had the references. Maybe 
tuesday...
