Nuclear localization of the ORF2 protein encoded by porcine circovirus type 2.
Infectious porcine circovirus type 2 (PCV2) was generated following transfection of a porcine retina cell line (VIDO R1) with cloned circovirus DNA. Expression of open reading frame 2 (ORF2) was detected at 24 h postinfection and onwards increasingly throughout the infection by Western blot analysis using ORF2 specific polyclonal antibody. Moreover, the ORF2 protein was also detected in purifie...
متن کاملIdentification and functional analysis of the novel ORF4 protein encoded by porcine circovirus type 2.
Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus-associated diseases in pigs. To date, viral proteins Cap, Rep, Rep', and ORF3, encoded by the PCV2 genome, have been described. Here, transcription and translation of a novel viral gene within the PCV2 genome (designated ORF4) was determined and functionally analyzed in vitro and in vivo. Northern blot analysi...
متن کاملIdentification of a new antigen epitope in the nuclear localization signal region of porcine circovirus type 2 capsid protein.
OBJECTIVE Porcine circovirus type 2 (PCV2) is the causative agent of postweaning multisystemic syndrome in pigs. The capsid (Cap) protein encoded by ORF2 is the main structural protein involved in the host immune protective response to PCV2. It is therefore important to map the antigenic epitopes of the PCV2 Cap protein. METHODS In this study, 5 monoclonal antibodies (mAbs) against the recomb...
متن کاملMapping of the nuclear localization signals in open reading frame 2 protein from porcine circovirus type 1.
Porcine circovirus type 1 (PCV1) contains two major open reading frames encoding the replication-associated proteins and the major structural capsid (Cap) protein. PCV1 Cap has an N-terminus carrying several potential monopartite or bipartite nuclear localization signals (NLS). The contribution of these partially overlapping motifs to nuclear importing was identified by expression of mutated PC...
متن کاملChanges in cellular microRNA expression induced by porcine circovirus type 2-encoded proteins
Porcine circovirus type 2 (PCV2) is the primary causative agent of postweaning multisystemic wasting syndrome, which leads to serious economic losses in the pig industry worldwide. While the molecular basis of PCV2 replication and pathogenicity remains elusive, it is increasingly apparent that the microRNA (miRNA) pathway plays a key role in controlling virus-host interactions, in addition to a...
