FIGURE 4.

Expression pattern of the Ufm1 system and putative interacting partners in C. elegans. The expression was set under the control of the respective promoter sequences (size, 2–3 kb) of the corresponding genes. Because no stage-specific expression was observed, only adult worms are displayed. The Ufm1 cascade and its potential binding partners are mainly expressed in the intestine. Neuronal expression could be observed in UfSP2, pUfm1, Ufbp1, Kel-8, and CDK5Rap3. The expression of UfSP2 and Ufbp1 in head neurons (possibly amphid neurons) is shown on the right.
