A novel gene encoding the α-chain of goose immunoglobulin heavy-chain (Igα) was cloned by reverse transcription-PCR. The cDNA had 1,760 bp and encompassed a partial V–D–J region of the heavy chain, a constant region (Cα) and 3′-untranslated region of α-chain. The Cα gene contains four constant region domains (CH1–CH4). Phylogenetic analysis indicated that(More)
A bovine interferon-kappa (BoIFN-κ) gene was amplified, which encodes a protein of 215 amino acids sharing 63% identity with human IFN-κ. BoIFN-κ was demonstrated to have antiviral and antiproliferative activities. Moreover, BoIFN-κ was shown to be highly sensitive to trypsin, however, it remained stable despite changes in pH and temperature. Result showed(More)
A bovine IFN-ε (BoIFN-ε) gene was amplified from bovine liver genomic DNA consisting of a 463bp partial 5'UTR, 582bp complete ORF and 171bp partial 3'UTR, which encodes a protein of 193 amino acids with a 21-amino acid signal peptide and shares 61 to 87% identity with other species IFN-ε. Then BoIFN-ε gene was characterized, and it can be transcribed in EBK(More)
A novel bovine interferon-ω (BoIFN-ω) gene, which encodes a protein of 195 amino acids with a 23-amino acid signal peptide, was amplified from bovine liver genomic DNA through PCR and named BoIFN-ω24 according to its position in the bovine genome. In this study, the recombinant protein was expressed in Escherichia coli and antiviral or antiproliferation(More)
Bovine interferon-omega3 (BoIFN-ω3) gene was amplified from bovine liver genomic DNA, which encodes a 195-amino acid protein containing a 23-amino acid signal peptide. Analysis of the molecular characteristics revealed that BoIFN-ω3 evolving from IFN-ω, contained four cysteine residues and five alpha helices, showing that BoIFN-ω3 presented the typical(More)
A novel goose immunoglobulin υ chain (Igυ) Fc fragment gene was cloned from splenic tissue mRNA using RT-PCR. Deduced amino acid sequence data from different vertebrates revealed high similarity to IgY-Fc fragments of duck (91%) and chicken (64%). Molecular characterization showed that the goose IgY-Fc fragment was consistent with the definition of(More)
