The endogenous Apc2 promoter drives expression of full-length, wild-type Apc2 which is tagged at the C-terminal end with a membrane targeting signal (Tag:PM(c-Ha-Ras)) and at the N-terminal end with EGFP.
The cuticle defects of embryos derived from Apc2g10 ApcQ8 males crossed to females containing double homozygous germline clones are strongly rescued by expression of Apc2T:Avic\GFP-EGFP,T:Mmmm\c-Ha-Ras. The embryonic lethality is partially rescued (41% lethality is seen).
Apc2EGFP,Tag:PM(c-Ha-Ras) partially rescues Apc2g10
Apc2T:Avic\GFP-EGFP,T:Mmmm\c-Ha-Ras rescues the cuticle defects of embryos lacking both maternal and zygotic Apc2[+] function (homozygous Apc2g10 embryos derived from Apc2g10 females). The embryonic lethality of these Apc2 mutants is partially rescued (34% embryonic lethality is seen), and viable adults are obtained.
