There are 4 genes (UACA, PTTG1IP, PIGR, CD81) of this GO term may interacted with ACTR2, EIF6 and hsa-miR-139-5p at the same time, and they play an important role in cancer associated pathway: apoptotic process (UACA, PTTG1IP) and immunity (PIGR, CD81). This evidence concerns the gene CD81 and cancer.
