Abstract:	Antisera generated against synthetic peptides were used to identify G-protein alpha-subunits in plasma membranes from rat adipocytes. Applying the immunoblot technique, we detected two Gs alpha-subunits of 42 and 43 kDa, corresponding to the two cholera toxin substrates, and two Gi alpha-subunits of 40 and 41 kDa, corresponding to the two pertussis toxin substrates present in these membranes. The 40 kDa protein was tentatively identified as the Gi2 alpha-subunit. A serum specific for the Go alpha-subunit failed to detect any immunoreactive protein. Thus plasma membranes of adipocytes possess two forms of Gi but not Go.
