Sequences encoding the cytoplasmic tail of if that were present in ifUAS.cMBa have been replaced with sequences encoding the cytoplasmic tail of mew.
if::mewUAS.cMBa, Scer\GAL4twi.PG, Scer\GAL4how-24B is a suppressor of lethal | recessive | embryonic stage phenotype of ifB4
if::mewUAS.cMBa/Scer\GAL448Y is a suppressor of lethal phenotype of mewM6
Partially rescues the first instar lethality of mewM6 homozygotes when expressed using Scer\GAL448Y.
