The entire coding region was targeted with sgRNAs targeting sequence upstream of the start codon and downstream of the stop codon (GCGCCCGGCGCCCTGACCGT, ACATGAGTTGGCGAGATCCC) using CRISPR/Cas9 technology, resulting in a 157,481 bp deletion. RT-PCR experiments confirmed the lack of transcription from this allele. (J:305611)
