The First Identified Nucleocytoplasmic Shuttling Herpesviral Capsid Protein: Herpes Simplex Virus Type 1 VP19C
VP19C is a structural protein of herpes simplex virus type 1 viral particle, which is essential for assembly of the capsid. In this study, a nuclear export signal (NES) of VP19C is for the first time identified and mapped to amino acid residues 342 to 351. Furthermore, VP19C is demonstrated to shuttle between the nucleus and the cytoplasm through the NES in a chromosomal region maintenance 1 (C...
متن کاملDNA Binding and Condensation Properties of the Herpes Simplex Virus Type 1 Triplex Protein VP19C
Herpesvirus capsids are regular icosahedrons with a diameter of a 125 nm and are made up of 162 capsomeres arranged on a T = 16 lattice. The capsomeres (VP5) interact with the triplex structure, which is a unique structural feature of herpesvirus capsid shells. The triplex is a heterotrimeric complex; one molecule of VP19C and two of VP23 form a three-pronged structure that acts to stabilize th...
متن کاملIntercellular Trafficking of VP22, a Herpes Simplex Virus Type 1 Tegument Protein
The herpes simplex virus type 1 (HSV-1) tegument protein, VP22 has been reported to have the property of intercellular transport. The previous studies have shown that following expression of a fusion protein containing VP22 it spreads to every cell in a monolayer and concentrates in the nucleus. In spite of these reports, some studies have shown that VP22 trafficking and its nucleus accumulatio...
متن کاملFunctional analysis of the triplex proteins (VP19C and VP23) of herpes simplex virus type 1.
The triplex of herpesvirus capsids is a unique structural element. In herpes simplex virus type 1 (HSV-1), one molecule of VP19C and two of VP23 form a three-pronged structure that acts to stabilize the capsid shell through interactions with adjacent VP5 molecules. The interaction between VP19C and VP23 was inferred by yeast cryoelectron microscopy studies and subsequently confirmed by the two-...
متن کاملExpression, Purification, and Antiserum Production of the Truncated UL31 Protein of Herpes Simplex Virus 1
Background: The UL31 protein of herpes simplex virus 1 (HSV-1) plays an important role in the HSV-1 replication, however, its pinpoint functions in the life cycle of the virus have yet to be adequately elucidated. Objectives: An antiserum specific for detecting HSV-1 UL31 was prepared as the foundation for future research on the role of UL31 in the course...
