Additionally, TARBP2 acts as a dsRNA‐dependent protein kinase (PKR) inhibitor to suppress the phosphorylation of eIF2α, thus enhancing cell mitosis and destabilizing transcripts to promote cancer metastasis, exhibiting miRNA‐independent properties in regulating cancer (Garcia et al., 2006; Goodarzi et al., 2014; Kim et al., 2014). This evidence concerns the gene TARBP2 and cancer.
