Construct: Amino acid replacement: H28A. Amino acid replacement: K30A. Amino acid replacement: K50E. Amino acid replacement: K51A. Amino acid replacement: K54A. Amino acid numbering starts from the first amino acid of the third double stranded RNA binding domain (dsRBD3).
100% of staudsRBD3mut, stau2 embryos die with head defects and no abdomen or pole cells.
staudsRBD3mut fails to rescue stau2
Addition of staudsRBD3mut to stau2 flies fails to rescue the stau phenotype.
