Genomic fragment ( 3L:19600040..19590604 , release 6 coordinates) that encompasses ash1 (sequence is derived from BAC clone CH322-147P9). The ash1 coding sequence has been mutated to carry the R1464A amino acid replacement. Coding sequence from the Taf6 gene is also present in this fragment; multiple ATG initiation codons in this CDS have been converted into stop codons.
ash1R1464A partially rescues ash122
ash1R1464A expressing ash122/ash122 animals that contain maternally deposited wild-type Ash1 protein and zygotically expressed Ash1 protein with the R1464A point mutation are fertile.
ash1R1464A/+ expressing ash122/ash122 animals that contain maternally deposited and zygotically expressed Ash1 protein with the R1464A point mutation exhibit similar homeotic transformations as ash122/ash122 pharate adults. A substantial fraction of them eclose from the pupal case but die in 1-2 days.
