Imprecise excision of {lacW}BRWD3s5349 has deleted genomic sequence from +172 (in exon1) to +948 (in exon4) relative to the start of the BRWD3 coding region.
eye disc & actin cytoskeleton | somatic clone
eye disc & nucleus | somatic clone
Somatic clones of BRWD3PX2 homozygous cells do not survive in the adult eye, but eyes developing from discs that contain such clones have visible scars. Retinal sections reveal these scars to be the result of incomplete ommatidia.
The nuclei of BRWD3PX2 homozygous cells in somatic clones in the late third instar eye disc fail to rise to the apical side of each cell posterior to the furrow as in wild-type. The actin cytoskeleton of these cells is disorganised.
