Glycoprotein D (gD) of herpes simplex virus (HSV) is required for successful infection. It is strongly implicated in virus penetration, in viral-induced cell-cell fusion, in exclusion of progeny virus and possibly, in stable attachment. However, the specific events that are mediated by gD and how it performs these functions is not yet known. The objective of this proposal is to determine the molecular basis of gD function for herpesviruses using biochemical, genetic, immunochemical and electron microscopy approaches. The specific aims are (a) to determine the step in HSV penetration that gD mediates that is hypothesized to differ form that mediated by other essential glycoproteins (gB and gH) (b) to determine other products besides gD that are required to mediate viral induced cell- cell fusion and (c) to determine functional similarity between gD and its homolog, gp50, in pseudorabies virus that it mediates a tighter adhesion between biological membranes. Evidence for or against this hypothesis will be provided by results from the proposed research. Understanding the molecular basis of gD function for HSV and PRV will provide information about critical events in herpesvirus entry and virus induced cell-cell fusion that will be relevant to other enveloped viruses which cause diseases. Since membrane fusion and membrane transit and frequent and essential biological events, this research will contribute to better understanding of this universal process.

单纯疱疹病毒 (HSV) 的糖蛋白 D (gD) 是 感染成功。 它与病毒的渗透密切相关， 病毒诱导的细胞-细胞融合，排除子代病毒，并且可能， 处于稳定的附着状态。 然而，由 gD 介导的特定事件 它如何执行这些功能尚不清楚。 的目标 该提案旨在确定 gD 功能的分子基础 利用生化、遗传、免疫化学和电子技术检测疱疹病毒 显微镜方法。 具体目标是 (a) 确定步骤 gD 介导的 HSV 渗透假设与以下形式不同 由其他必需糖蛋白（gB 和 gH）介导 (b) 以确定 除了 gD 之外，介导病毒诱导的细胞-所需的其他产品 细胞融合和 (c) 确定 gD 及其之间的功能相似性 伪狂犬病病毒中的同系物 gp50 介导更紧密的粘附 生物膜之间。 支持或反对这一假设的证据将 由拟议研究的结果提供。 了解 HSV 和 PRV gD 功能的分子基础将提供信息 关于疱疹病毒进入和病毒诱导细胞的关键事件 与其他包膜病毒相关的融合会导致 疾病。 由于膜融合和膜转运频繁且 重要的生物事件，这项研究将有助于更好地 理解这个普遍的过程。
