Class iii fusion protein
WebThere are three classes of fusion protein, class I fusion proteins (for example haemagglutinin (HA) from IAV), class II fusion proteins (for example, E protein of Dengue virus), and class III ... WebThe class III fusion proteins are employed by herpesviruses, rhabdoviruses and baculoviruses. This class features characteristics of both class I and class II fusion proteins. For example, they have a helical and a central β-stranded domain bearing one or more fusion loops. This is the case of rhabdoviral G proteins, which contrast class I ...

WebAug 30, 2024 · Class III fusion proteins are identified in vesicular stomatitis virus (VSV) glycoprotein G, herpes simplex virus glycoprotein B (gB), and baculoviruses. The pre-fusion and post-fusion structures of VSV-G have been studied but only the post-fusion structure of other two viruses are reported so far (Rey and Lok 2024). WebX-ray crystallography of three class II fusion proteins — the E proteins of TBE and dengue virus, and the E1 protein of SFV — has revealed a common fold for these proteins, which is ...
WebJan 15, 2024 · Viral fusion proteins are categorized into three distinct classes: I, II and III. As a class III fusion protein, gB is composed of α-helices and β-sheets, and contains two fusion loops per protomer. Class III fusion proteins are found in herpesviruses, vesicular stomatitis virus (VSV) and baculovirus. The VSV fusion protein, G, is the best ...

WebMay 29, 2024 · Although gB structurally resembles autonomous class III fusion proteins, it strictly depends on gH/gL to drive membrane fusion. Whether the gH/gL complex needs to be membrane anchored to fulfill its function and which role the gH cytoplasmic (CD) and transmembrane domains (TMD) play in fusion is unclear. While the gH CD and TMD …
