UASt regulatory sequences drive expression of svr with its carboxypeptidase-like domain 3 replaced by carboxypeptidase-like domain 1B.
svr1B-2-1B-t2.UAS/Scer\GAL4svr-PG33 partially rescues svrPG33
Expression of svr1B-2-1B-t2.Scer\UAS driven by Scer\GAL4svr-PG33 partially rescues the lethality associated with svrPG33/Y hemizygosity.
