Has also been shown to inhibit the replication of mammalian viruses. The protein may provide a means of cellular suicide upon invasion by a virus.CATALYTIC ACTIVITY:Endohydrolysis of the N-glycosidic bond at one specific adenosine on the 28S rRNA.SUBUNIT:Monomer.SIMILARITY:Belongs to the ribosome-inactivating protein family.Type 1 RIP subfamily."
