Amino acid replacement K759M, which results in a kinase-inactive form of Eph.
Expression of EphK579M.Scer\UAS.T:Hsap\MYC under the control of any one of Scer\GAL4elav-C155, Scer\GAL4sca-537.4, Scer\GAL4elav.PLu, Scer\GAL4ftz.ng, Scer\GAL4A80 or Scer\GAL4GMR.PF does not result in a mutant phenotype.
Expression of EphK579M.Scer\UAS.T:Hsap\MYC under the simultaneous control of Scer\GAL4sca-537.4 and Scer\GAL4elav.PLu does not result in a mutant phenotype.
