"The
mtd-1::gfp fusion (TU#677) contains 2.5 kb 50 of the start codon, all the introns, all the coding sequence except the sequence for the last 51 amino acids, and a synthetic transmembrane domain (Fig. 4C)... Both TU#677 and TU#676 are expressed exclusively in the six touch receptor neurons, as identified by their positions and projections, throughout development, beginning in embryogenesis (Fig. 4A). A
mec-3 mutation (
u6) abolished the expression of fusion TU#677 (Fig. 4B), confirming the results of the Northern blot (Fig. 2)."
