CRISPR-Cas9-guided oncogenic chromosomal translocations with conditional fusion protein expression in human mesenchymal cells.

abstract：:The L-A double-stranded RNA virus of Saccharomyces cerevisiae makes a gag-pol fusion protein by a -1 ribosomal frameshift. The pol amino acid sequence includes consensus patterns typical of the RNA-dependent RNA polymerases (EC 2.7.7.48) of (+) strand and double-stranded RNA viruses of animals and plants. We have carr...
