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 shutt...

Descripción
Sumario: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 (CRM1)-dependent manner involving RanGTP hydrolysis. This makes VP19C the first herpesviral capsid protein with nucleocytoplasmic shuttling property and adds it to the list of HSV-1 nucleocytoplasmic shuttling proteins.
