The 3′-portion of the genome of a U.S. isolate of the porcine reproductive and respiratory syndrome (PRRS) virus, ATCC VR-2332, was cloned and sequenced. The resultant 3358 nucleotides contain 6 open reading frames (ORFs) with homologies to ORFs 2 through 7 of the European strain of the PRRS virus and other members of the free-standing genus of(More)
The middle (M) RNA segment of Rift Valley fever virus (RVFV) encodes four proteins: the major viral glycoproteins G2 and G1, a 14-kilodalton (kDa) protein, and a 78-kDa protein. These proteins are derived from a single large open reading frame (ORF) present in the virus-complementary M-segment mRNA. We used recombinant vaccinia viruses in which sequences(More)
The Phlebovirus Rift Valley fever virus (RVFV), like other members of the Bunyaviridae family, matures intracellularly at the smooth-surfaced vesicles in the Golgi region of infected cells. Here we show that in cultured cells the RVFV glycoproteins G2 and G1 accumulate and are retained at this site. To investigate the parameters governing this subcellular(More)
Recombinant vaccinia viruses were constructed and used in conjunction with site-specific antisera to study the coding capacity and detailed expression strategy of the M segment of the Phlebovirus Rift Valley fever virus (RVFV). The M segment could be completely and faithfully expressed in recombinant RVFV-vaccinia virus-infected cells, the gene products(More)
The M segment RNA of Rift Valley fever virus (RVFV) encodes four gene products: the two viral envelop glycoproteins G2 and G1, a glycosylated 78-kDa protein, and a nonglycosylated 14-kDa protein. These proteins are generated from a single open reading frame (ORF) by a strategy involving independent translational initiations at both the first and second(More)
This report describes the cloning and characterization of expressed gene sequences of the swine and bovine interferon-gamma inducible chemokine CXCL11, or I-TAC, associated with type 1 T-helper immune responses, and affirmation of bioactivity of their yeast-expressed protein products. The coding regions of both cDNA sequences were 303 nucleotides in length;(More)
