UAS regulatory sequences drive expression of a mutant form of Hsap\RUNX1::Hsap\RUNX1T1 in which CBFβ binding has been abrogated through replacement of the tyrosine at residue 113 and the threonine at residue 161 with alanines.
Expression of Hsap\RUNX1::Hsap\RUNX1T1YT.Scer\UAS.cSa under the control of Scer\GAL4Hml.Δ has no effect on third instar larval hemocyte numbers.
