Molecular structure and characterization of the cytokine TWEAK and its receptor Fn14 in bovine.

Full-length cDNA encoding TWEAK and Fn14 from bovine was isolated. We used bioinformatics to analyze the gene structure, function, evolutionary relationships, and predicted three-dimensional structure of proteins and binding sites. Real-time quantitative PCR (Q-PCR) analysis revealed that both TWEAK and Fn14 are constitutively expressed in various tissues in bovine.
