Herpes simplex virus 1 (HSV-1) UL31 is a multifunctional protein and important for HSV-1 infection. Pseudorabies virus (PRV) UL31 is a late protein homologous to HSV-1 UL31. Previous studies showed that PRV UL31 is predominantly localized to nucleus, however, the molecular determinants for its nuclear import were unclear to date. Here, by utilizing live(More)
The pseudorabies virus (PRV) UL31 protein (pUL31) is a homologue of the herpes simplex virus 1 pUL31, which is a multifunctional protein that is important for HSV-1 infection. However, little is known concerning the subcellular localization signal of PRV UL31. Here, by transfection with a series of PRV UL31 deletion mutants fused to an enhanced yellow(More)
Herpes simplex virus 1 (HSV-1) ICP22 is a multifunctional protein and important for HSV-1 replication. Pseudorabies virus (PRV) ICP22 (P-ICP22) is a homologue of HSV-1 ICP22 and is reported to be able to selectively modify the transcription of different kinetic classes of PRV genes, however, the subcellular localization, localization signal and molecular(More)
As an important protein, UL31 has been demonstrated to play multiple roles in herpes simplex virus 1 (HSV-1) replication. Previous studies showed that UL31 predominantly locates in the nucleus in chemical fixed cells and live cells, however, the determining mechanisms for its nuclear translocation is not clear. In the present study, by utilizing live cells(More)
We have recently discovered unusual sugar chains [xylose-glucose and (xylose)2-glucose] linked to a serine residue in the first epidermal growth factor (EGF)-like domains of human and bovine coagulation factors VII, IX, and protein Z. The sequence surrounding this serine residue has a common -Cys-X-Ser-X-Pro-Cys- structure. Since one (residues 533-538) of(More)
As a crucial protein, the herpes simplex virus 1 (HSV-1) UL2 protein has been shown to take part in various stages of viral infection, nonetheless, its exact subcellular localization and transport molecular determinants are not well known thus far. In the present study, by using live cells fluorescent microscopy assay, UL2 tagged with enhanced yellow(More)
Thrombospondin is a major glycoprotein of the platelet alpha-granule and is secreted during platelet activation. Several protease-resistant domains of thrombospondin mediate its interactions with components of the extracellular matrix including fibronectin, collagen, heparin, laminin, and fibrinogen. Thrombospondin, as well as fibronectin, is composed of(More)
The herpes simplex virus 1 (HSV-1) UL31 protein is a multifunctional nucleoprotein that is important for viral infection; however, little is known concerning its subcellular localization signal. Here, by transfection with a series of HSV-1 UL31 deletion mutants fused to enhanced yellow fluorescent protein (EYFP), a bipartite nuclear localization signal(More)
