Protein trap-induced mutant phenotype affecting the dhx37 gene. (A–D) Bright field images of dhx37ws0977Tg/+ sibling (A), homozygous dhx37ws0977Tg/ws0977Tg mutant (B), dhx37 ATG morpholino-injected (C), or full-length dhx37 RNA-injected homozygous mutant embryo (D). (E) The Ds insertion in chr8:4765207-4765215 is linked to the mutant phenotype. Black arrows indicate the position of primers used for genotyping PCRs. (F–H) RT-PCR results from homozygous dhx37ws0977Tg/ws0977Tg embryos show that the bcl2 splice acceptor sequence trapped endogenous upstream splice donor sites in the dhx37 gene, producing multiple fusion transcripts (F, G), leading to the disruption of wild-type transcripts (H). (G) The main fusion products, 1 and 2, are out of frame with respect to the reading sequence. Black arrows in the schematic in (F) indicate the positions of primers used for RT-PCR. No evidence of wild-type transcripts was found, and only mutant fusion transcripts were detected. The fusion transcripts always have a 71-bp linker sequence (SA) originated from bcl2 splice acceptor site left between upstream exons and the mCherry reporter sequence. The major fusion transcripts 1 and 2 are out of frame for mCherry coding sequences (G).
