UAS regulatory sequences drive expression of a kinase-dead Hsap\ABL1::Hsap\BCR fusion protein; a mutation has been introduced into the P-loop of the tyrosine kinase domain.
Expressing Hsap\ABL1::Hsap\BCRKD.UAS under the control of Scer\GAL4GMR.PU does not affect eye development.
Expressing Hsap\ABL1::Hsap\BCRKD.UAS under the control of Scer\GAL4dome.PU does not induce melanotic masses in third instar larvae.
