cbp-1 : mec-7

"Using a-MEC-7 antibody (gift of G. Ruvkun, Massachusetts General Hospital, Boston, MA), we found MEC-7 expression in all four touch receptor neurons in wild-type embryos where it is detectable in both the cell body and axonal extensions. One such cell is shown in Figure 2e (the other three positive cells are in different focal planes). Five to 10 MEC-7-positive cells were found in terminal stage embryos lacking CBP-1 expression and these cells showed evidence of axon outgrowth consistent with neuronal differentiation (Fig. 2f)."
