Many host proteins can also function as cofactors for viral entry, such as heparin sulfate proteoglycans, C-type lectins, neuropilin-1 and furin [ 10 - 13 ]. (ijbs.com)
Inadequate understanding of the antigenic intricacies of its viral proteins and the immune responses they generate in the host is the greatest obstacle to the progress of hRSV prevention and treatment. (fortunejournals.com)
The lipid envelope surrounding the nucleocapsid is derived from the host cell plasma membrane during the budding process. (fortunejournals.com)
The cystovirus Pseudomonas phage phi6 has an envelope that harbors five viral membrane proteins and phospholipids derived from the cytoplasmic membrane of its Gram-negative host. (biomedcentral.com)

tural proteins to form the virion. (what-when-how.com)

The major difference between the two families is that members of the family Rudiviridae are not enveloped, whereas nucleocapsids of lipothrixviruses are surrounded by a lipid membrane. (wikipedia.org)

Description: SARS S1 [His], recombinant protein from E. coli. (microarraystation.com)
Description: SARS-CoV E Protein ( 34.7 kDa), recombinant protein from E. coli, 1 mg/mL. (microarraystation.com)
Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. (bio-techne.com)

The S2 subunit mediates viral cell membrane fusion by forming a six-helical bundle via the twoheptad repeat domain. (novelconceptsmedical.com)

A third small domain at the C-terminal tail appears to have an ordered alpha helical secondary structure and may be involved in the formation of higher-order oligomeric assemblies. (wikipedia.org)
Working with partners at the Pasteur Institute and French National Institute for Agricultural Research (Institut National de la Recherche Agronomique - INRA) we recently published an atomic resolution model of the RSV nucleocapsid - a helical structure comprising the viral genome and N protein.

Genome Eight negative sense ssRNA molecules, each encoding one protein. (powershow.com)
Our results suggest that these molecules may represent the stepping-stone for the future development of NC-inhibitors capable of targeting the protein itself and its recognition site in RNA. (pasteur.fr)
The inner fluid can contain cargo molecules such as nucleic acids or soluble proteins. (biomedcentral.com)

MS/MS experiments showed that the protein cargo of large LpA-I particles was more diverse. (cdc.gov)
