Rat Wfs1 exon 5-specific zinc-finger nucleases (ZNFs) and microinjection-ready mRNA were injected to embryos harvested from female Sprague-Dawley rats (Crl: CD(SD) )rats. Thereafter, microinjected egg cells were transferred to the oviduct of pseudopregnant Sprague-Dawley recipients.Three different Wfs1 mutant rat lines were created: Wfs1em1 ( Wfs1-ex5-KO232), Wfs1em2 (Wfs1-ex5-KO266) and Wfs1em3 (Wfs1-ex5-INS244). Wfs1em3 rats carry a substitution in exon 5 of the Wfs1 gene, which is predicted to result in a substitution of LQK (aa 224-226)
into YCMNTI in the WFS1 protein.
