Insertion of a genomic Cirl fragment at the attP site in CirlKO.attP.w-; the fragment contains an mRFP(Unk) cassette inserted into an exon encoding part of the extracellular domain (ECD; this results in at least 2nm elongation of the ECD) and also contains a w+* marker.
The responses of CirlN-RFP mutant lch5 neurons in larvae to mechanical stimulation are slightly reduced, compared to controls.
