Deletion in the isoform-specific C-terminal exon of the lola-E isoform (this exon encodes the zinc-finger motif), resulting in a specific knockout of the lola-E isoform.
Neural stem cell proliferation does not seem to be affected in lolaKO.E larval brains, as they the brain lobe size and the number of type I neuroblasts per lobe are comparable to controls.
