Mutations in the cytoplasmic tail of herpes simplex virus 1 gH reduce the fusogenicity of gB in transfected cells.

Abstract excerpt

Mutations within the cytoplasmic tail (cytotail) of herpes simplex virus 1 (HSV-1) gH were previously observed to suppress the syncytial phenotype of gB cytoplasmic domain mutant A855V in infected cells. Here, we examined the effects of gH cytotail mutations on virus-free cell-cell fusion in transfected cells to exclude the contributions of viral proteins other than gD, gH/gL, and gB. We show that a truncation at...
