== Function ==
[https://www.uniprot.org/uniprot/L_CCHFI L_CCHFI] Displays RNA-directed RNA polymerase, deubiquitinating and deISGylase activities. RNA-dependent RNA polymerase is responsible for replication and transcription of the viral RNA genome. The deubiquitinating activity cleaves both ubiquitinated and ISGylated products and may therefore regulate ubiquitin and ISG15 dependent innate immunity.

== Publication Abstract from PubMed ==
Active-site directed probes are powerful in studies of enzymatic function. We report an active-site directed probe based on a warhead so far considered unreactive. By replacing the C-terminal carboxylate of ubiquitin (Ub) with an alkyne functionality, a selective reaction with the active-site cysteine residue of de-ubiquitinating enzymes was observed. The resulting product was shown to be a quaternary vinyl thioether, as determined by X-ray crystallography. Proteomic analysis of proteins bound to an immobilized Ub alkyne probe confirmed the selectivity toward de-ubiquitinating enzymes. The observed reactivity is not just restricted to propargylated Ub, as highlighted by the selective reaction between caspase-1 (interleukin converting enzyme) and a propargylated peptide derived from IL-1beta, a caspase-1 substrate.
