"The
unc-52(
ra515) and
unc-52(
gk3) alleles result from deletions of exons 15 through 18 encoding four Domain IV Ig repeats, or exons 28 through 37 encoding the C-terminal Domain V of UNC-52, respectively (Mullen et al., 1999)... DTC migrations are normal in these strains, and the frequency of DTC migration defects in double mutants of
unc-52(
ra515);
unc-5(
e152) and
unc-52(
gk3);
unc-5(
e152) are not significantly different from
unc-5(
e152) alone (P > 0.1; Table 1)."
