A αTub84B promoter drives expression of th coding sequences containing an amino acid replacement in the RING domain.
Amino acid replacement: C406Y.
Diap1C406Y.αTub84B is a non-suppressor of increased cell death phenotype of rprGMR.PW
Diap1C406Y.αTub84B is a non-suppressor of eye phenotype of rprGMR.PW
Expression of thC406Y.αTub84B, which lacks a functional RING domain, fails to inhibit the small-eye phenotype observed in rprGMR.PW mutants.
