  • Patent number: 7488805
    Abstract: The present invention is directed to novel apoptosis polypeptides such as the Apop1, Apop2, and Apop3 proteins and related molecules which are involved in modulating apoptosis and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention. Further provided by the present invention are method for identifying novel compositions which modulate the biological activity of Apop1, Apop2, and Apop3, and the use of such compositions in diagnosis and treatment of disease.

  • Patent number: 6645766
    Abstract: The invention provides shuttle vectors, and methods of using shuttle vectors, capable of expression in, at least, a mammalian cell. Furthermore, the shuttle vectors are capable of replication in at least yeast, and optionally, bacterial cells. Also provided is a method wherein yeast are transformed with a shuttle vector as provided herein. Heterologous nucleic acids flanked by 5′ and 3′ ends identical to a homologous recombination site within the shuttle vector are introduced to the transformed yeast and allowed to homologously recombine with the shuttle vector such that they are inserted into the vector by the yeast organism. The shuttle vector is then recovered and transferred to a mammalian cell for expression.
