| + | [[http://www.uniprot.org/uniprot/UCRP_HUMAN UCRP_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> | ||
