An Hsp83 promoter drives expression of wild-type Tfb5, which is tagged at the C-terminal end with Tag:polyHis.
Larvae expressing Tfb5C.Hsp83.T:Zzzz\His6 show a greater resistance to UV irradiation than control flies.
One copy of Tfb5C.Hsp83.T:Zzzz\His6 rescues the viability and all other defects (sterility and held-out wing phenotype) seen in Tfb5SH1279 homozygotes.
