A: Diagram of the Tg(ef1α:MuRF1a-GFP) and Tg(ef1α:MuRF2a-GFP) transgenes. The full-length coding sequences of zebrafish murf1a or murf2a were cloned in frame upstream of the EGFP coding sequence in the pT2AL200R150G vector. The pT2AL200R150G vector contained an elongation factor-1 alpha (EF-1α) gene promoter. Transgenic zebrafish were generated using these two transgenes.
B-D: Subcellular localization of MuRF1a-GFP (B), MuRF1a-GFP (D), or XBP1-GFP fusion protein in myofibers of the respective transgenic zebrafish embryos at 28 hpf. Scale bar: 30 μm.
