A novel antisense RNA ASPACT confers multi-level suppression of PACT and associated signalling.

ABSTRACT: The innate immune system is the frontline host protection against pathogens. Effective antiviral immunity is elicited upon recognition of viral RNAs by the host pattern recognition receptors. One of the major viral RNA sensors is retinoic acid inducible gene-1, which triggers the production of interferons (IFNs). In turn, this protective response requires another viral sensor and immunity factor interferon-inducible protein kinase RNA activator (PACT/PRKRA). Here, we report the identification and characterization of a novel antisense PACT gene that expresses a non-coding RNA in a convergent and interferon-inducible manner. Publicly available gene structure and expression data revealed that this gene, that we termed ASPACT, overlaps with the 3' -end of the PACT locus an
