Détails sur OAS2

Antigène: OAS2 (2'-5'-Oligoadenylate Synthetase 2, 69/71kDa (OAS2))

Autre désignation: Oas2

Sujet: OAS2 antibody detects 2'-5'-oligoadenylate synthetase 2, a double-stranded RNA-activated enzyme encoded by the OAS2 gene located on chromosome 12q24.13. OAS2 plays a central role in the innate immune response to viral infection by synthesizing 2'-5'-linked oligoadenylates (2-5A) upon activation by viral double-stranded RNA. These 2-5A molecules subsequently activate RNase L, leading to degradation of viral and cellular RNA and inhibition of viral replication. OAS2 is expressed in most tissues but is strongly upregulated in response to interferon signaling, particularly in immune cells such as macrophages, dendritic cells, and lymphocytes.

Structurally, OAS2 is a 113 kDa protein containing two functional OAS catalytic domains, allowing higher polymerization activity than other family members such as OAS1. It belongs to the 2'-5'-oligoadenylate synthetase family of nucleotidyltransferases, characterized by a conserved polymerase fold and dsRNA-binding motifs. OAS2 localizes to the cytoplasm, often associating with ribosomes and endoplasmic reticulum membranes where viral replication typically occurs.

Functionally, OAS2 acts as a critical antiviral effector enzyme in interferon-stimulated pathways. Upon recognition of viral RNA, OAS2 catalyzes ATP polymerization into 2-5A molecules that bind and activate latent RNase L. This leads to RNA cleavage, apoptosis of infected cells, and amplification of antiviral signaling. OAS2 also interacts with pattern recognition receptors such as MDA5 and RIG-I, coordinating interferon response cascades. In addition to antiviral defense, OAS2 influences immune regulation, apoptosis, and inflammatory cytokine expression.

OAS2 expression is strongly induced by type I and type III interferons. Genetic variants in OAS2 have been associated with altered susceptibility to viral infections including SARS-CoV-2, hepatitis C, and West Nile virus. Dysregulation of OAS2 can contribute to autoimmune disorders through excessive RNA degradation. Pathway associations include interferon signaling, RNA decay, and innate immune activation. During development, OAS2 expression in immune progenitors supports early antiviral competence.

The OAS2 antibody from NSJ Bioreagents is a valuable reagent for studying antiviral mechanisms, interferon signaling, and immune regulation.
