DESCRIPTION

Also known as RSAD2_MOUSE, Rsad2, Vig1. Interferon-inducible antiviral protein which plays a major role in the cell antiviral state induced by type I and type II interferon. Catalyzes the conversion of cytidine triphosphate (CTP) to 3'-deoxy-3', 4'-didehydro-CTP (ddhCTP) via a SAM-dependent radical mechanism. In turn, ddhCTP acts as a chain terminator for the RNA-dependent RNA polymerases from multiple viruses and directly inhibits viral replication. Therefore, inhibits a wide range of DNA and RNA viruses (By similarity). Promotes also TLR7 and TLR9-dependent production of IFN-beta production in plasmacytoid dendritic cells (pDCs) by facilitating 'Lys-63'-linked ubiquitination of IRAK1 by TRAF6. Plays a role in CD4+ T-cells activation and differentiation. Facilitates T-cell receptor (TCR)-mediated GATA3 activation and optimal T-helper 2 (Th2) cytokine production by modulating NFKB1 and JUNB activities. Can inhibit secretion of soluble proteins (By similarity) (PubMed:17686841, PubMed:19047684, PubMed:21435586, PubMed:21880757). Homodimer. Interacts with IRAK1 and TRAF6 (PubMed:21435586). Interacts with FPPS. Interacts with HADHB. Interacts (via C-terminus) with VAPA/VAP33 (via C-terminus) (By similarity).
