FIGURE 1.
Generation of CRISPR/Cas9-mediated homozygous point mutation in the CPAP/CENPJ gene. (A) The scheme of homologous recombination between endogenous CPAP wild-type (WT) and exogenous repair template (single strain DNA, ssDNA) harbored A>T point mutation. Black inverted triangle: Cas9-cutting site. (B) Sanger sequencing results of two independent mutant clones displaying homozygous A>T point mutation in exon 16 of CPAP, which resulted in Glutamic acid (E) being replaced by Valine (V) at amino acid 1235. (C) CPAP protein expression level in WT and two independent mutant hiPSC clones. Black star symbol indicated non-specific bands.
