Target

Full Name

2'-5'-Oligoadenylate Synthetase 1

Introduction

This gene is induced by interferons and encodes a protein that synthesizes 2',5'-oligoadenylates (2-5As). This protein activates latent RNase L, which results in viral RNA degradation and the inhibition of viral replication. Alternative splicing results in multiple transcript variants with different enzymatic activities. Polymorphisms in this gene have been associated with susceptibility to viral infection and diabetes mellitus, type 1. Diseases associated with OAS1 include Diabetes Mellitus, Insulin-Dependent and Hand, Foot And Mouth Disease. Among its related pathways are Cytokine Signaling in Immune system and Innate Immune System. An important paralog of this gene is OAS3.

Function

Interferon-induced, dsRNA-activated antiviral enzyme which plays a critical role in cellular innate antiviral response (PubMed:34581622).
In addition, it may also play a role in other cellular processes such as apoptosis, cell growth, differentiation and gene regulation. Synthesizes higher oligomers 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 (PubMed:34581622).
Can mediate the antiviral effect via the classical RNase L-dependent pathway or an alternative antiviral pathway independent of RNase L. The secreted form displays antiviral effect against vesicular stomatitis virus (VSV), herpes simplex virus type 2 (HSV-2), and encephalomyocarditis virus (EMCV) and stimulates the alternative antiviral pathway independent of RNase L.
Isoform p46
When prenylated at C-terminal, acts as a double-stranded RNA (dsRNA) sensor specifically targeted to membranous replicative organelles in SARS coronavirus-2/SARS-CoV-2 infected cells where it binds to dsRNA structures in the SARS-CoV-2 5'-UTR and initiates a potent block to SARS-CoV-2 replication. Recognizes short stretches of dsRNA and activates RNase L. The binding is remarkably specific, with two conserved stem loops in the SARS-CoV-2 5'- untranslated region (UTR) constituting the principal viral target (PubMed:34581622).
The same mechanism is necessary to initiate a block to cardiovirus EMCV (PubMed:34581622).
Isoform p42
Not prenylated at C-terminal, is diffusely localized and unable to initiate a detectable block to SARS-CoV-2 replication.

PTM

Isoform p46
Prenylated at C-terminal. C-terminal prenylation is necessary to initiate a block to SARS-CoV-2 and is associated with protection from severe COVID-1. The prenylated form is targeted to perinuclear structures rich in viral dsRNA, whereas the non-prenylated form is diffusely localized and unable to initiate a detectable block to SARS-CoV-2 replication (Probable). C-terminal prenylation is also necessary to initiate a block to cardiovirus EMCV (Probable).
Isoform p42
Not prenylated at C-terminal. The non-prenylated form is diffusely localized and unable to initiate a detectable block to SARS-CoV-2 replication.
