Figure 2.

WldS variant proteins are stably expressed in Drosophila neurons. Three independent UAS-driven transgene insertion lines for each WldS variant molecule were crossed to elav-Gal4, and protein extracts from heads were assayed for expression using α-Nmnat1 antibodies. Multiple lines for each construct were found to express detectable levels of protein. The expression of each of these molecules in ORNs with OR22a-Gal4 did not lead to expression of proteins at levels detectable by Western blot analysis (not depicted). Molecular masses are shown in kilodaltons. MW, molecular weight.
