    摘要: Disclosed is a method for determining whether a first protein is capable of physically interacting with a second protein. The method involves: (a) providing a host cell which contains (i) a reporter gene operably linked to a protein binding site; (ii) a first fusion gene which expresses a first fusion protein, the first fusion protein including the first protein covalently bonded to a binding moiety which is capable of specifically binding to the protein binding site; and (iii) a second fusion gene which expresses a second fusion protein, the second fusion protein including the second protein covalently bonded to a weak gene activating moiety; and (b) measuring expression of the reporter gene as a measure of an interaction between the first and the second proteins. Such a determination facilitates the isolation of the gene encoding the interacting protein. Also disclosed herein is recombinant Cdi1 polypeptide, nucleic acid encoding the Cdi1 polypeptide, and uses thereof.

    摘要: A method for the identification of compounds as inhibitors of oncoprotein action is described. A compound is identified as an inhibitor of oncoprotein action based on its ability to modulate the transcription of a reporter gene. Transcription of the reporter gene is dependent upon the binding of a fusion oncoprotein to a specific DNA binding element positioned upstream of the reporter gene promoter. The fusion oncoprotein contains a transcriptional regulatory domain from an oncoprotein and a DNA binding domain from a different protein.

    摘要: Regulation of eucaryotic gene expression is controlled by procaryotic peptides. The peptides recognize specific DNA sequences present in the gene, which may be derived from procaryotic genes, and either activate or repress gene transcription. Hybrid procaryotic peptides may be used containing both repressor and activator peptides.

    摘要: A method of identifying substances in a material handling work environment that analyzes sensor input from the environment with an image processor to extract features of the substance using optical flow and object recognition, and operates a vector modeler and a particle modeler to generate multiple predictions about particle movement within the substance based on existing data models for physical properties to generate multiple predictions of physical properties of the substance.

Also disclosed are methods for assaying protein interactions, and identifying antagonists and agonists of protein interactions. Proteins isolated by these methods are also discussed. Finally, populations of eukaryotic cells are disclosed, each cell having a recombinant DNA molecule encoding a conformationally-constrained intracellular peptide.
