UASt regulatory sequences drive expression of spn-F in which all the Ser residues that can be phosphorylated by IKKε have been mutated to Ala (amino acid replacements S53A, S85A, S172A, S202A, S264A, S270A, S349A and S325A), resulting in a phospho-deficient form of spn-F. The protein is tagged with EGFP.
Scer\GAL4ppk.PG/spn-F8A.UAS.EGFP partially rescues spn-F2
spn-F8A.Scer\UAS.T:Avic\GFP-EGFP expression driven by Scer\GAL4ppk.PG partially rescues impaired dendrite pruning in spn-F2/spn-F2 pupae (16h after puparium formation).
