Figure 2. Expression pattern of anexp-2::GFP reporter fusion. GFP fused to the COOH-terminus of
exp-2 is strongly expressed in (A) the pharyngeal muscle and amphid neurons in the anterior portion of the worm and (B) phasmid neurons and the intestinal muscle in the posterior portion of the worm. Theexp-2::GFP fusions contain the
exp-2promoter and coding regions encoded by an Nae I to Sal I fragment from the cosmid F12F3 fused to a Sal I to Apa I fragment from pPD95.77 (gift from A. Fire, J. Ahnn, G. Seydoux, and S. Xu) containing GFP coding sequences and the
unc-54 3' untranslated region.
