UNC-40::GFP is ventrally localized in the unc- 40
(ur304) mutant or in
unc-40(1) animals, but is more evenly distributed in
unc-6(
rh46) mutants. In unc- 40
(ur304);
unc-6(
rh46) mutants, UNC-40TGFP localization is shifted dorsally. The
unc-40(
ur304) mutation alone causes no cell or axon migration defects such as those caused by other
unc-40 alleles.
