This invention concerns materials, methods and applications relating to the multimerizing of protein mediators of biological events using synthetic, preferably non-peptidic, dimerizing agents or CIDs.
摘要:
The present invention provides compositions and methods for evaluating the likelihood that a tumor is sensitive to an mTOR inhibitor, e.g., rapamycin or a rapamycin analog. The invention provides FKBP proteins as biomarkers for predicting the likelihood that a tumor is sensitive to an mTOR inhibitor. The methods include assessing the expression or activity of an FKBP protein, e.g., FKBP 12, in a subject with a tumor or in a sample derived from a tumor. Additional biomarkers and biomarker combinations are also provided. The invention also provides kits containing, e.g., a validated antibody or ligand for assessing the expression or activity of an FKBP protein.

摘要:
Materials and methods involving conditional retention domains (CRDs) are disclosed. A conditional retention domain is any domain which is retained in the ER or other secretory compartment in the absence of ligand and is released from the secretory machinery when ligand is bound, i.e. in the presence of ligand. Also disclosed are fusion proteins containing CRDs and cells expressing such fusion proteins. In addition, the invention provides novel methods for producing target proteins in vivo using fusion proteins containing conditional retention domains and methods for identifying novel CRDs.
摘要:
The present invention relates to novel fusion proteins which activate transcription, to nucleic acid constructs encoding the proteins and their use in the genetic engineering of cells. Key fusion proteins of the invention contain at least two mutually heterologous domains, one of which being a bundling domain. Bundling domains include any domain that induces proteins that contain it to form multimers ('bundles') through protein-protein interactions with each other or with other proteins containing the bundling domain. Examples of bundling domains that can be used in the practice of this invention include domains such as the lac repressor tetramerization domain, the p53 tetramerization domain, a leucine zipper domain, and domains derived therefrom which retain observable bundling activity. Cells are engineered by the introduction of recombinant nucleic acids encoding the fusion proteins, and in some cases with additional nucleic acid constructs, to render them capable of ligand-dependent regulation of transcription of a target gene. Administration of the ligand to the cells then regulates (positively, or in some cases, negatively) target gene transcription.
