The prion protein gene (PrP) encodes a cellular protein of unknown function. A conformational isoform of this protein is involved in the neurodegenerative prion diseases. To facilitate the identification of structurally and antigenically important regions within the PrP molecule, the rabbit PrP open reading frame (ORF) was cloned and characterised. There is 82-87% identity at the nucleotide sequence...
Bovine adenovirus type 2 (BAV2) is a medium size double-stranded DNA virus which infects both bovine and ovine species, resulting in mild respiratory and gastrointestinal disorders. To better understand the virus and its growth characterisitics in Madin-Darby bovine kidney (MDBK) cells, we have cloned and sequenced the extreme right-end segment of the BAV2 genome (90.5–100 map units). Analysis of...
We have used the methylotrophic yeast, Pichia pastoris, to express the open reading frame 3 (ORF3) of the hepatitis E virus (HEV). The ORF3 gene codes for a 123-amino-acid protein that contains highly immunodominant epitopes and is a potentially useful diagnostic and immunoprophylactic antigen. The expressed protein showed positive on immunoblots probed against antibodies raised in rabbit and infected...
In recent studies it has been suggested that long reading frames on the antisense strand of open reading frames (ORFs) are more frequent than expected. The vertebrate DNA database was searched for long (greater than 900 bp) antisense non-stop reading frames (aNRFs) that overlap known coding regions. The sequences obtained were predominantly positioned in DNA with a high usage of G or C in the third...
