Activation 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...
متن کاملHigher Expression Level and Lower Toxicity of Genetically Spliced Rotavirus NSP4 in Comparison to the Full-Length Protein in E. coli
Background: Rotavirus group A (RVA) is recognized as a major cause of severe gastroenteritis in children and new-born animals. Nonstructural protein 4 (NSP4) is responsible for the enterotoxic activity of these viruses in the villus epithelial cells. Amino acids 114-135 of NSP4 are known to form the diarrhea-inducing region of this viral enterotoxin. Therefore, developing an NSP4 lacking the en...
متن کاملPeptide based polyclonal antibody production against bovine rotavirus non structure protein4 (NSP4)
The rotavirus nonstructural protein 4 (NSP4), is a multi functional protein that play key role in both viral morphogenesis and cytopathic effect associated with cell death. However, the complete biological effect of NSP4 remains to be clarified. Since to obtain further knowledge about this protein there is a need for recognizing antibody and there is no commercial antibody against this protein,...
متن کاملEXPRESSION OF NONSTRUCTURAL GLYCOPROTEIN NSP4 OF SAIl SIMIAN ROTAV IRUS IN ESCHERICHIA COLI AND PRODUCTION OF ANTIBODY AGAINST IT
Rotavirus nonstructural glycoprotein NSP4 can induce diarrhea in newborn mice. It has been suggested that NSP4 may be a key determinant for rotavirus pathogenesis and a target for vaccine development. In order to study the biological and morphological role of NSP4 a large amount of the purified protein and antibody against it are required. Simian rotavirus SA11 was propagated in BSCl cell,...
متن کاملبیان و خنثی‌سازی گلیکوپروتئین نوترکیب روتا ویروس میمونی((NSP4 با آنتی‌بادی اختصاصی در نوزاد موش
Background and Objectives: Rotaviruses are the most important cause of severe diarrhea in infants and young children in both developed and developing countries. Rotaviruses are members of the reoviridae family and contain 11 double- stranded RNA segments. Segment 10 encodes nonstructural glycoprotein NSP4, that can induce diarrhea in newborn mice. It has been suggested that NSP4 may be a key de...
