Deletion in the isoform-specific C-terminal exon of the lola-T isoform (this exon encodes the zinc-finger motif), resulting in a specific knockout of the lola-T isoform.
lolaKO.T homozygous stage 14 embryos show disrupted gonad formation, with disrupted germ cell migration. Stage 15/16 embryos do not show ventral nerve defects.
