[[http://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. [[http://www.uniprot.org/uniprot/ISG15_HUMAN ISG15_HUMAN]] Ubiquitin-like protein that is conjugated to intracellular target proteins after IFN-alpha or IFN-beta stimulation. Its enzymatic pathway is partially distinct from that of ubiquitin, differing in substrate specificity and interaction with ligating enzymes. ISG15 conjugation pathway uses a dedicated E1 enzyme, but seems to converge with the Ub conjugation pathway at the level of a specific E2 enzyme. Targets include STAT1, SERPINA3G/SPI2A, JAK1, MAPK3/ERK1, PLCG1, EIF2AK2/PKR, MX1/MxA, and RIG-1. Deconjugated by USP18/UBP43. Shows specific chemotactic activity towards neutrophils and activates them to induce release of eosinophil chemotactic factors. May serve as a trans-acting binding factor directing the association of ligated target proteins to intermediate filaments. May also be involved in autocrine, paracrine and endocrine mechanisms, as in cell-to-cell signaling, possibly partly by inducing IFN-gamma secretion by monocytes and macrophages. Seems to display antiviral activity during viral infections.<ref>PMID:1373138</ref> <ref>PMID:7526157</ref> <ref>PMID:8550581</ref> <ref>PMID:2005397</ref> <ref>PMID:16254333</ref> <ref>PMID:16009940</ref>  In response to IFN-tau secreted by the conceptus, may ligate to and regulate proteins involved in the release of prostaglandin F2-alpha (PGF), and thus prevent lysis of the corpus luteum and maintain the pregnancy (By similarity).<ref>PMID:1373138</ref> <ref>PMID:7526157</ref> <ref>PMID:8550581</ref> <ref>PMID:2005397</ref> <ref>PMID:16254333</ref> <ref>PMID:16009940</ref>
