| malfunction | RNaseT2 family members are implicated in human pathologies such as cancer and parasitic diseases. Humans lacking RNASET2 manifest a defect in neurological development, perhaps due to aberrant control of the immune system. Mutations in RNASET2 are identified as the causative lesion in an autosomal recessive disorder leading to cystic leukoencephalopathy, overview | Homo sapiens |
| additional information | comparisons of basic structure and function of RNaseT2 family members and their biological roles. Ribonucleases of the T2 family are transferase-type RNases and are classified by their similarity to the RNase T2 protein from Aspergillus oryzae | Homo sapiens |

| physiological function | ACTIBIND inhibits the clonogenicity and invasiveness of various tumors in culture and in mouse models. ACTIBIND disrupts the fine actin networks at the interior of colon cancer cells. Interaction of RNaseT2 proteins with the actin cytoskeleton provides a possible mechanism for RNase-independent cytotoxicity | Aspergillus niger |
| physiological function | RNaseT2 omega-1 is the major component in priming dendritic cells for Th2 polarization of CD4+ T cells during infection, a process depending on the RNase activity of omega-1 | Schistosoma mansoni |
| physiological function | RNaseT2 protein secreted by the purine auxotroph Entamoeba histolytica might function in scavenging purines from this amoeba's host | Entamoeba histolytica |
