Peter Belshaw has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6011018
    Abstract: Dimerization and oligomerization of proteins are general biological control mechanisms that contribute to the activation of cell membrane receptors, transcription factors, vesicle fusion proteins, and other classes of intra- and extracellular proteins. We have developed a general procedure for the regulated (inducible) dimerization or oligomerization of intracellular proteins. In principle, any two target proteins can be induced to associate by treating the cells or organisms that harbor them with cell permeable, synthetic ligands. To illustrate the practice of this invention, we have induced: (1) the intracellular aggregation of the cytoplasmic tail of the .zeta.
    Type: Grant
    Filed: May 29, 1998
    Date of Patent: January 4, 2000

    Inventors: Gerald R. Crabtree, Stuart L. Schreiber, David M. Spencer, Thomas J. Wandless, Peter Belshaw
  • Patent number: 5994313
    Abstract: We have developed a general procedure for the regulated (inducible) dimerization or oligomerization of intracellular proteins and disclose methods and materials for using that procedure to regulatably initiate cell-specific apoptosis (programmed cell death) in genetically engineered cells.
    Type: Grant

  • Patent number: 5871753
    Abstract: Methods and compositions are provided for modified cells, where a chimeric protein consisting of a ligand binding domain fused to an action domain is employed which initiates a signal which activates a biological process: transcription of at least one gene, usually a second construct introduced into the host cells; exocytosis; or an extracellular process. The second construct optimally present provides for a promoter which responds to a transcriptional activation action domain to provide for transcription, when an appropriate ligand binds to the ligand binding domain. Exemplary of the system is the use of an FKBP/CD3.zeta. or transcription factor fusion protein, using dimeric FK506 or FK520 as the ligand and a promoter responsive to NF-AT or other transcription factor requiring two molecules for transcriptional activation.
