Molecular cloning and functional characterization of porcine DEAD (Asp-Glu-Ala-Asp) box polypeptide 41 (DDX41)
چکیده انگلیسی
DEAD (Asp-Glu-Ala-Asp) box polypeptide 41 (DDX41), a member of the DEXDc helicase family, was recently identified as an intracellular DNA sensor in mouse myeloid dendritic cells. In this study, porcine DDX41 (poDDX41) was cloned and its role in the type I interferon (IFN) signaling pathway was investigated in porcine kidney (PK-15) cells. Full-length poDDX41 cDNA encodes 622 amino acid residues and contains a DEADc domain and a HELICc domain. poDDX41 mRNA is widely expressed in different tissues, especially the stomach and liver. Overexpression of poDDX41 in PK-15 cells induced IFN-β by activating transcription factors IRF3 and NF-κB. Knockdown of poDDX41 with siRNA significantly reduced IFN-β expression induced by poly(dA:dT), a double-stranded DNA (dsDNA) analogue, or pseudorabies virus, a dsDNA swine virus. Therefore, poDDX41 is involved in the dsDNA- and dsDNA-virus-mediated type I IFN signaling pathway in porcine kidney cells.
