FIGURE 3.
Developmentally regulated expression of C14B1.10, the C. elegans ABH8 ortholog. A–D, PC14B1.10gfp, a fusion of the C14B1.10 promoter to the GFP gene, shows expression in neuronal (smaller arrows) and non-neuronal (large arrow) cells. Expression is higher and more widely distributed at the early larval stage (A), reduced at the middle larvae stage (B), and almost exclusively detected in neuronal cells in the head (C) and tail (D) of adult animals. E and F, C14B1.10::GFP, the GFP protein fused to the C14B1.10 protein under its endogenous promoter control, is exclusively localized to the cytoplasm. Arrows indicate the positions of selected neurons in the head (E) and tail (F) of an adult animal. Scale bars, 5 μm.
