Other genes that are frequent sites of integration are ARIH2 (a cancer-related gene involved in acute myeloid leukemia and gastric cancer) [61,76,77], MKL1 (a gene related to MKL2), MROH1 (encoding large multiple HEAT-repeat-containing proteins) [61,78], and XPO6 (encoding an importin-beta protein that mediates the nuclear export of profilin–actin complexes) [61,79]. This evidence concerns the gene MRTFB and cancer.
