An Hsp83 promoter drives expression of the mei-218 coding region tagged at the N-terminal end with Tag:FLAG. The SV40 3'-UTR is present downstream of the mei-218 stop codon.
Can rescue the X and 4th chromosome nondisjunction phenotype of mei-2186 females. Rescue is variable (from complete through to no rescue), depending on the P{Hsp83-mei-218.FLAG-SV40} insertion line used.
