UASt regulatory sequences drive expression of the C terminal end of pbl-RA (amino acids 716-844) tagged at the C-terminal end with Tag:HA.
No defects in early mesodermal development are observed when pblC-term.Scer\UAS.T:Ivir\HA1 is expressed in stage 8 embryos under the control of the Scer\GAL4twi.2PE and Scer\GAL4Mef2.PR drivers.
