UASt regulatory sequences drive expression of an mbl isoform (GenBank: JN12969) encoding an 940 amino acid polypeptide with two tandem zinc finger (TZF) motifs.
Expression of mblScer\UAS.940aa under the control of Scer\GAL4da.G32 rescues the embryonic lethality of mbl398, but the transgene fails to restore adult viability.
