Q:

The strain for this is listed as Rotavirus A, and we want to know if this also wA strain rotarix.

A:
Thanks for your inquiry.
Rotavirus is the most common cause of diarrhoeal disease among infants and young children.[1] It is a genus of double-stranded RNA viruses in the family Reoviridae.
Nearly every child in the world is infected with rotavirus at least once by the age of five.[2] Immunity develops with each infection, so subsequent infections are less severe; adults are rarely affected.[3] There are nine species of this virus, referred to as A, B, C, D, E, F, G, H and I. Rotavirus A, the most common species, causes more than 90% of rotavirus infections in human.

靶點(diǎn)詳情

  • 功能：
    Spike-forming protein that mediates virion attachment to the host epithelial cell receptors and plays a major role in cell penetration, determination of host range restriction and virulence. Rotavirus attachment and entry into the host cell probably involves multiple sequential contacts between the outer capsid proteins VP4 and VP7, and the cell receptors. It is subsequently lost, together with VP7, following virus entry into the host cell. Following entry into the host cell, low intracellular or intravesicular Ca(2+) concentration probably causes the calcium-stabilized VP7 trimers to dissociate from the virion. This step is probably necessary for the membrane-disrupting entry step and the release of VP4, which is locked onto the virion by VP7. During the virus exit from the host cell, VP4 seems to be required to target the newly formed virions to the host cell lipid rafts.; Forms the spike 'foot' and 'body' and acts as a membrane permeabilization protein that mediates release of viral particles from endosomal compartments into the cytoplasm. During entry, the part of VP5* that protrudes from the virus folds back on itself and reorganizes from a local dimer to a trimer. This reorganization may be linked to membrane penetration by exposing VP5* hydrophobic region. In integrin-dependent strains, VP5* targets the integrin heterodimer ITGA2/ITGB1 for cell attachment.; Forms the head of the spikes and mediates the recognition of specific host cell surface glycans. It is the viral hemagglutinin and an important target of neutralizing antibodies. In sialic acid-dependent strains, VP8* binds to host cell sialic acid, most probably a ganglioside, providing the initial contact. In some other strains, VP8* mediates the attachment to histo-blood group antigens (HBGAs) for viral entry.
