Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to
assemble and peer-review its pathway modules. The integration of ORCID within Reactome
enables us to meet a key challenge with authoring, curating and reviewing biological
information by incentivizing and crediting the external experts that contribute their
expertise and time to the Reactome curation process. More information is available at
ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please
forward this information to us and we will update your Reactome pathway records.

| text | Ribonuclease L (RNase L) is an ankyrin (ANK) repeat domain containing dual endoribonuclease-pseudokinase which is encoded by RNASEL gene (Wreschner DH et al. 1982; Zhou A et al.1993; Hassel BA et al. 1993; Huang H et al. 2014; Han Y et al. 2014). Activated RNase L forms a homodimer (Dong B & Silverman RH 1995) which cleaves within single-stranded regions of different RNA substrates, predominantly after UpAp and UpUp dinucleotides, leaving 2',3'-cyclic phosphoryl and 5'-hydroxyl groups at the termini of the RNA cleavage products (Wreschner DH et al. 1981; Floyd-Smith G et al. 1981; Han Y et al. 2012; Cooper DA et al. 2014). The antiviral function of RNase L extends beyond direct cleavage of viral RNA and includes also cleavage of cellular RNA such as mRNA and rRNA that is required for viral replication (Wreschner DH et al. 1981; Silverman RH et al.1983; Brennan-Laun SE et al. 2014; Cooper DA et al. 2014). RNase L induces apoptosis to eliminate virus-infected cells and autophagy to limit viral infections in some circumstances (Zhou A et al. 1997; Castelli JC et al. 1997; Chakrabarti A et al. 2012). Depending on the cell type and basal levels of RNase L, viral and cellular RNA cleavage products induce signaling to the IFN beta gene through RIG-I and/or MDA5 and MAVS (Malathi K et al. 2007; Banerjee S etl al. 2014). |
