title: Molecular cloning of feline Fas antigen and Fas ligand cDNAs.
abstract: The Fas antigen (FasA) and Fas ligand (FasL) are key molecules which mediate apoptosis. For investigation of apoptosis in cats, we isolated molecular clones of feline FasA and FasL cDNAs by using the polymerase chain reaction (PCR) method to amplify cDNAs from feline lymphoma cell lines. These feline FasA and FasL clones contained complete open reading frames encoding 314 and 280 amino acids, respectively. These feline FasA and FasL cDNA clones had structures characteristic of the tumor necrosis factor (TNF) receptor family and TNF family, respectively. The deduced amino acid sequence of feline FasA and feline FasL, respectively showed 45.0%-60.0% and 75.0%-90.0% similarity with their human, mouse and bovine counterparts. These data will be helpful for investigating the role of the FasA and FasL system in apoptosis and for studying the various diseases associated with the deregulation of apoptosis in cats.
