pim promoter sequences drive expression of a mutated pim ORF and 3'UTR; the destruction box has been mutated from KKPLGNLDN to AKPAGNLDA and the KEN motif found near the N-terminal end of the coding sequence has been mutated to AAA. The coding sequence is tagged with Tag:MYC. Generated by excision of the FRT stop cassette from pimkenadba.g.FRT.Tag:MYC.
