UASt regulates expression of GFP-tagged αTub84B in which lysine (K) 40 is mutated to glutamine (Q), which mimics acetylated α-tubulin.
Scer\GAL4VP16.nanos.UTR/αTub84BK40Q.UAS.GFP is a suppressor of egg chamber phenotype of lkyKO
αTub84BK40Q.UAS.GFP/Scer\GAL4tj.PU is a non-suppressor of egg chamber phenotype of lkyKO
