E-G Protein interactions in co-IP from fed or starved
Drosophila third instar larvae. Starvation induces
in vivo interaction between (E) endogenous
Drosophila Rab21 (IP) and Sbf, (F) endogenous Rab21 (IP) and fat body-expressed GFP:Vamp7 (anti-GFP IB) and (G) endogenous Sbf (IP) and fat body-expressed GFP:VAMP7 (anti-GFP IB). See also
