UAS regulatory sequences drive expression of a mutant form of Hsap\RUNX1::Hsap\RUNX1T1 in which DNA binding has been abrogated through replacement of the arginine at residue 174 with glutamine.
Expression of Hsap\RUNX1::Hsap\RUNX1T1R174Q.Scer\UAS.cSa under the control of Scer\GAL4Hml.Δ has no effect on third instar larval hemocyte numbers.
