Lethal in transheterozygous combination with Med4.
MedD5 dominantly enhances the tkv6 phenotype; tkv6 homozygotes have a normal notum and legs, but the presence of one copy of MedD5 results in defects in the notum and legs. Double heterozygotes with Df(2L)tkv2 may show imaginal disc development defects. No interaction with put135 is seen in double heterozygous flies.
Selected as: Dominant enhancer of the tkv6 phenotype.
