Purified recombinant rotavirus VP7 forms soluble, calcium-dependent trimers.
Rotavirus is a major cause of severe, dehydrating childhood diarrhea. VP7, the rotavirus outer capsid glycoprotein, is a target of protective antibodies and is responsible for the calcium-dependent uncoating of the virus during cell entry. We have purified, characterized, and crystallized recombinant rhesus rotavirus VP7, expressed in insect cells. A critical aspect of the purification is the e...
متن کاملTwo proline residues are essential in the calcium-binding activity of rotavirus VP7 outer capsid protein.
Rotavirus maturation and stability of the outer capsid are calcium-dependent processes. It has been shown previously that the concentration of Ca2+-solubilizing outer capsid proteins from rotavirus particles is dependent on the virus strain. This property of viral particles has been associated with the gene coding for VP7 (gene 9). In this study the correlation between VP7 and resistance to low...
متن کاملRecombinant Outer Capsid Glycoprotein (VP7) of Rotavirus Expressed in Insect Cells Induces Neutralizing Antibodies in Rabbits
BACKGROUND Rotaviruses cause diarrhea in infants and young children worldwide. Rotavirus outer capsid protein, VP7 is major neutralizing antigen that is important component of subunit vaccine to prevent rotavirus infection. Many efforts have been done to produce recombinant VP7 that maintain native characteristics. We used baculovirus expression system to produce rotavirus VP7 protein and to st...
متن کاملActivation of calcium/calmodulin-dependent kinase II following bovine rotavirus enterotoxin NSP4 expression
Objective(s): The rotavirus nonstructural protein 4 (NSP4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase C-dependent and phospholipase C-independent pathways in infected cells. It is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...
