    摘要: The invention relates to a method of detecting and analyzing protein interactions in a cell, which comprises the steps: d) provision of the activity of at least one enzyme from the group consisting of recombinases and proteases in the cell as a result of a protein interaction, e) continual generation of an active reporter protein in the cell in question as a result of the enzymic activity of step a) for a period of time which exceeds the duration of the protein interaction of step a), f) generation of a detection signal by the reporter proteins generated in b). The invention furthermore relates to reverse embodiments of the method above of detecting and analyzing protein interactions in a cell, with, as a result of the induced dissociation of a defined interaction between proteins, the activity of at least one enzyme from the group consisting of recombinases and proteases being provided in the cell and converted to a permanent detection signal of said cell. The invention moreover relates to cells expressing the protein components of the invention and to kits providing the protein components of the invention at the DNA level in the form of suitable expression vectors and, where appropriate, suitable transfectable or injectable cells. The cells provided may, where appropriate, express stably or transiently individual protein components of the invention.

    摘要: The present invention is concerned with the provision of screening assays. More specifically it relates to a method to a method for determining whether an exogenous stimulus is capable of eliciting at least one biological response in a host cell comprising the steps of (i) applying the said stimulus to a host cell which comprises a plurality of different polynucleotide constructs each construct comprising a unique expressed tag (EXT) operatively linked to an expression control sequence whose activity can be exclusively modulated by one specific signalling pathway or cellular sensor implemented in said host cell, said signalling pathway or cellular sensor being involved in eliciting a biological response and being sensitive for the exogenous stimulus, (i) determining the amount of at least one expressed tag; and (iii) comparing the amount of the at least one unique expressed tag to a suitable reference amount, whereby it is determined whether the exogenous stimulus is capable of eliciting at least one biological response in the host cell.
