Construction of larsb-knockout mutant zebrafish line. (A) Diagram showing the larsb genomic locus, CRISPR/Cas9 target site, and larsb-knockout (larsb−/−) zebrafish mutant genotype. The sgRNA target sequence is displayed in green and the PAM region in red. In the genomic sequencing analysis chromatograms, the deletion region in the mutant larsb−/− zebrafish is shown by the red box. (B) The Lars protein of larsb−/− zebrafish had a missing editing domain. Western blot analysis of the Larsb protein expression in larsb+/+ and larsb−/− zebrafish. β-actin levels served as the loading control. Larsb: leucyl-tRNA synthetase b.
