Chain A,B   (RIP1_PHYAM | P10297)
molecular function
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0030598    rRNA N-glycosylase activity    Catalysis of the hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from rat ribosomes or corresponding sites in 28S RNA from other species.
biological process
    GO:0006952    defense response    Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
    GO:0051607    defense response to virus    Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
    GO:0017148    negative regulation of translation    Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
