Intercellular 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 کاملCharacterization of major recognition sequences for a herpes simplex virus type 1 origin-binding protein.
To investigate early initiation events in the replication of herpes simplex virus type 1, we analyzed interactions of proteins from infected cell extracts with the small origin of herpes simplex virus type 1 (oris1). Using the mobility shift assay, we detected two origin-specific binding interactions. We characterized the more prominent interaction on both strands of the DNA duplex with DNase I...
متن کاملThe major transcriptional regulatory protein of herpes simplex virus type 1 includes a protease resistant DNA binding domain.
Herpes simplex virus type 1 expresses five immediate-early (IE) polypeptides. In the absence of functional Vmw175 (the product of IE gene 3) activation of transcription of later classes of viral genes and repression of IE gene expression does not occur. The recognition of specific DNA sequences by Vmw175 requires, as determined by sensitivity to mutation, a part of the protein highly conserved ...
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 کاملMapping of epitopes on the 65k DNA-binding protein of herpes simplex virus type 1.
Previously we have described the isolation of seven monoclonal antibodies (MAbs) and two polyvalent rabbit sera directed against the product of herpes simplex virus type 1 (HSV-1) gene UL42, a 65K DNA-binding protein (65KDBP) which is essential for HSV DNA replication and virus growth. We now report the synthesis of all 483 overlapping hexapeptides of this 488 amino acid protein and describe th...
