UASt regulatory sequences drive expression of a C-terminally truncated form of klu which lacks sequence encoding the fourth Zn finger through to the end of the wild-type protein. The protein is tagged with a Tag:HA epitope.
Expression of kluΔzf4.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4wor.PA fails to induce supernumerary type II neuroblasts in the larval brain.
