Fig. 3. UNC-51 and BEC-1 deficiency suppresses touch insensitivity in mec-4(u231) and deg-1(u506) mutants. Ex, Ex[pbec-1::BEC-1::GFP + rol-6(su1006)] genotype. Because unc-51 mutant animals are paralyzed, we scored their ability to shift the anterior or posterior body region upon touching. For each double mutant genotype n=150, P<0.0001 (unpaired t-test). Data are mean ± s.e.m.
