UAS regulates expression of Manf containing a C129S substitution, a mutation that destroys the CXXC motif and prevents the formation of the C-terminal disulphide bridge.
ManfC129S.Scer\UAS expression driven by Scer\GAL4da.G32 does not rescue the early larval lethality of ManfΔ96 mutants, though one of three insertions did result in very few rescued pupae.
