Heterotrimeric G proteins have been found in the nucleus (look for
papers by Michael Crouch), endosomes, caveolae (that probably counts
as cell membranes) and other organelles. I am not aware of reports
localizing G proteins to mitochondria or the endoplasmatic reticulum
(except during synthesis :-).
