Human regulatory proteins HNRNPA1 (heterogeneous nuclear ribonucleoprotein A1), HNRNPC, HNRNPL, HuR (human antigen R), and protein LIN28A (lin-28 homolog A) were predicted to bind ebv-sisRNA-1 and/or ebv-sisRNA-2; FUS (fused in sarcoma) was predicted to associate with ebv-sisRNA-2. This evidence concerns the gene HNRNPC and sarcoma.
