UAS regulatory sequences drive expression of a mutant form of Hsap\RUNX1::Hsap\RUNX1T1 in which the NHR3 and MYND domains have been deleted (amino acid 542 onwards).
Expression of Hsap\RUNX1::Hsap\RUNX1T1NHR2X.Scer\UAS.cSa under the control of Scer\GAL4Hml.Δ increases proliferation of circulating hemocytes, but the effect is not as severe as when the wild type fusion gene (Hsap\RUNX1::Hsap\RUNX1T1Scer\UAS.cSa) is expressed.
