In addition, it may also play a role in other cellular processes such as apoptosis, cell growth, differentiation and gene regulation. Synthesizes preferentially dimers of 2'-5'- oligoadenylates (2-5A) from ATP which then bind to the inactive monomeric form of ribonuclease L (RNase L) leading to its dimerization and subsequent activation. Activation of RNase L leads to degradation of cellular as well as viral RNA, resulting in the inhibition of protein synthesis, thus terminating viral replication. Can mediate the antiviral effect via the classical RNase L-dependent pathway or an alternative antiviral pathway independent of RNase L. Displays antiviral activity against Chikungunya virus (CHIKV), Dengue virus, Sindbis virus (SINV) and Semliki forest virus (SFV). {ECO:0000269|PubMed:19056102, ECO:0000269|PubMed:19923450, ECO:0000269|PubMed:9880533}. |OAS1 C| |NTP transf 2| |2-5-oligoadenylate synthetase activity| |regulation of ribonuclease activity| |regulation of nuclease activity| |negative regulation of viral genome replication| |type I interferon signaling pathway| |cellular response to type I interferon| |double-stranded RNA binding| |response to type I interferon| |interferon-gamma-mediated signaling pathway| |negative regulation of viral life cycle| |regulation of viral genome replication| |negative regulation of viral process| |regulation of viral life cycle| |cellular response to interferon-gamma| |response to interferon-gamma| |defense response to virus| |regulation of viral process| |negative regulation of multi-organism process| |regulation of symbiosis, encompassing mutualism through parasitism| |response to virus| |cytokine-mediated signaling pathway| |intracellular membrane-bounded organelle| |innate immune response| |regulation of multi-organism process| |defense response to other organism| |cellular response to cytokine stimulus| |immune effector process| |response to cytokine| |regulation of hydrolase activity| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |ATP binding| |extracellular space| |immune response| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp11|CCCP 1μM R00 exp11]]|1.75| No correlation found to any other genes in chemogenomics.
