Cloning and sequence analysis of VP1, VP2 and VP3 genes of Indian chicken anemia virus
Chicken anemia virus was detected by PCR in tissue samples collected from poultry flocks in Gujarat,India. The VP1, VP2 and VP3 gene sequences of CAV from Anand, Gujarat were obtained after cloning thePCR products in pDrive cloning vector. Nucleotide sequence alignment with other CAV sequencesdemonstrated overall identity of 95-98.8%, 98.8-99.8% and 98.8-100% for VP1, VP2 and VP3 regions,respec...
متن کاملLocation of the dsRNA-dependent polymerase, VP1, in rotavirus particles.
Double-stranded RNA (dsRNA) viruses transcribe and replicate RNA within an assembled, inner capsid particle; only plus-sense mRNA emerges into the intracellular milieu. During infectious entry of a rotavirus particle, the outer layer of its three-layer structure dissociates, delivering the inner double-layered particle (DLP) into the cytosol. DLP structures determined by X-ray crystallography a...
متن کاملBioinformatic prediction of polymerase elements in the rotavirus VP1 protein.
Rotaviruses are the major cause of acute gastroenteritis in infants world-wide. The genome consists of eleven double stranded RNA segments. The major segment encodes the structural protein VP1, the viral RNA-dependent RNA polymerase (RdRp), which is a minor component of the viral inner core. This study is a detailed bioinformatic assessment of the VP1 sequence. Using various methods we have ide...
متن کاملMolecular evolution of the VP1, VP2, and VP3 genes in human rhinovirus species C
Human rhinovirus species C (HRV-C) was recently discovered, and this virus has been associated with various acute respiratory illnesses (ARI). However, the molecular evolution of the major antigens of this virus, including VP1, VP2, and VP3, is unknown. Thus, we performed complete VP1, VP2, and VP3 gene analyses of 139 clinical HRV-C strains using RT-PCR with newly designed primer sets and next...
متن کاملThe N terminus of rotavirus VP2 is necessary for encapsidation of VP1 and VP3.
The innermost core of rotavirus is composed of VP2, which forms a protein layer that surrounds the two minor proteins VP1 and VP3, and the genome of 11 segments of double-stranded RNA. This inner core layer surrounded by VP6, the major capsid protein, constitutes double-layered particles that are transcriptionally active. Each gene encoding a structural protein of double-layered particles has b...
