term viral protein refers to both the products of the genome of a virus and any host proteins incorporated into the viral particle. Viral proteins are...

between host cells. Not all viruses have envelopes. A viral envelope protein or E protein is a protein in the envelope, which may be acquired by the capsid...

In virology, a nonstructural protein is a protein encoded by a virus but that is not part of the viral particle. They typically include the various enzymes...

the protein in the viral envelope, and a short tail in the interior of the virion. They may also form protein–protein interactions with other viral proteins...

independent viral particles, or virions, consisting of (i) genetic material, i.e., long molecules of DNA or RNA that encode the structure of the proteins by which...

correspond to individual proteins, are called capsomeres. The proteins making up the capsid are called capsid proteins or viral coat proteins (VCP). The capsid...

shuts off protein synthesis in the host, degrades host mRNA, helps in viral replication, and regulates gene expression of viral proteins. The viral genome...

A viral structural protein is a viral protein that is a structural component of the mature virus. Examples include the SARS coronavirus 3a and 7a accessory...

portion of the protein furthest from the viral surface while the S2 regions form a flexible "stalk" containing most of the protein-protein interactions...

identify viral proteins, or parts of proteins, that can be disabled. These "targets" should generally be as unlike any proteins or parts of proteins in humans...

structure. Each protomer consists of four polypeptides known as VP (viral protein) 1, 2, 3 and 4. VP2 and VP4 polypeptides originate from one protomer...

small number of viral proteins, invariably establishing cooperative associations among HIV proteins and between HIV and host proteins, to invade host...

of CD35. To enter epithelial cells, viral protein BMRF-2 interacts with cellular β1 integrins. Then, viral protein gH/gL interacts with cellular αvβ6/αvβ8...

the viral contents into the cell and initiating the infectious cycle. As the sole viral protein on the surface of the virus, the envelope protein is a...

viral regulatory and accessory protein is a type of viral protein that can play an indirect role in the function of a virus. An example is Nef. Viral...

Viral matrix proteins are structural proteins linking the viral envelope with the virus core. They play a crucial role in virus assembly, and interact...

size. M forms protein-protein interactions with all three other major structural proteins. M is necessary but not sufficient for viral assembly; M and...

machinery and the low- molecular-weight precursors for the synthesis of viral proteins and nucleic acids. Virus replication occurs in seven stages: Attachment...

codes for one protein, except genes 9, which codes for two. The RNA is surrounded by a three-layered icosahedral protein capsid. Viral particles are up...

results indicate overall reduction in protein synthesis but indicated no specificity for a sole reduction of viral protein synthesis. In recent years, studies...

(N) protein is a protein that packages the positive-sense RNA genome of coronaviruses to form ribonucleoprotein structures enclosed within the viral capsid...

Covalently bonded to the 5’ UTR is the viral protein VPg which aids in viral entry and replication. 2A and 3C are viral proteinases which aid in the cleavage...
