What is glycoprotein in Ebola?
Ebola virus glycoprotein (GP) is the only protein that is expressed on the surface of the virus. The GP proteins play critical roles in the entry of virus into cell and in the evasion of the immune system. The GP gene transcript to membrane GP is constituted of two subunits GP1 and GP2, and the secretory GP (sGP).
How was PCR used for Ebola?
The RT-PCR and antigen-capture diagnostic assays proved very effective for detecting ebolavirus in patient serum, plasma, and whole blood. In samples collected very early in the course of infection, the RT-PCR assay could detect ebolavirus 24 to 48 h prior to detection by antigen capture.
Is Ebola single stranded or double?
The virion nucleic acid of Ebola virus consists of a single-stranded RNA with a molecular weight of approximately 4.0 x 10(6).
What do glycoproteins do for viruses?
The surface glycoproteins of an enveloped virus attach the virion to a target host cell by properly interacting with a cellular receptor [22]. Structural biological analysis of viral envelope glycoproteins reveals that viruses have wide range of folds to facilitate their attachment with proper host receptors.
What is the genetic material of Ebola virus?
Ebola virus causes the disease called Ebola hemorrhagic fever. The genetic material is single-stranded RNA surrounded by the nucleoprotein and various other components present inside the nucleocapsid. This nucleocapsid is enclosed in a viral envelope.
What genome type is Ebola?
Ebola virus particles have at their core a viral nucleocapsid composed of a helical single stranded RNA genome wrapped around viral proteins NP, VP35, VP30, and L.
Is Ebola a DNA virus?
Ebolaviruses belong to the group of nonsegmented negative strand (NNS) RNA viruses. Most members of the Ebolavirus genus cause severe disease in humans. Here, we report that ebolaviruses have evolved a genome replication mechanism that distinguishes them from the other NNS RNA viruses.
What types of viruses have glycoproteins?
Table 1
| Name of the Virus | Glycoproteins identified | Specific role |
|---|---|---|
| Zaire Ebola virus | Spike Protein Gp1-Gp2 [64] | Primary Host cell activation [64] |
| Dengue virus | E (dimer) [64] | Host cell fusion and attachment [64] |
| Chikungunya virus | E1 and E2 [41, 51] | Host cell binding |
How many genes does Ebola virus have?
Ebola virus (EBOV), member of genus Ebolavirus, family Filoviridae, have a non-segmented, single-stranded RNA that contains seven genes: (a) nucleoprotein (NP), (b) viral protein 35 (VP35), (c) VP40, (d) glycoprotein (GP), (e) VP30, (f) VP24, and (g) RNA polymerase (L).
