Description

Nucleotide substitution: G4268A. Mutation is within the catalytic domain.

(LeMosy et al., 2000)

The protease domain of this allele has been sequenced. Amino acid replacement: G1334R. Residue G1334 is a highly conserved glycine just two residues C-terminal to the active site. Nucleotide substitution: a G to A transition.

      Allele is inactive in dorsoventral polarity establishment.

      (LeMosy et al., 2000)

      Dorsalised embryos. dec-1-marked clones exhibit no defects in dorsoventral patterning.

      (Nilson and Schupbach, 1998)

      Class II allele. Affected embryos show dorsalization. Eggs are not fragile.

      ndl9/ndl3 and ndl1/ndl3 are as severely defective in both dorsal ventral patterning and eggshell integrity as ndl3 itself.
