    摘要: This invention relates to industrial production of proteins. More specifically, the invention relates to a method for obtaining cells that stably express a protein of interest, even when cultivated in the absence of selective pressure. DHFR is used as a surrogate marker. The transfected cells are not selected based on resistance to a toxic compound, but based on fluorescence as measured by FACS using fluorescent MTX.

    摘要: The present invention relates to complexes of the CDK2 protein with proteins identified as interacting with CDK2 by a modified yeast two hybrid assay system. The proteins identified to interact with CDK2 are cyclin H, cyclin I, ERH, and two gene products, hsReq*-1 and hsReq*-2, which are splice variants of the gene hsReq. Thus, the invention provides complexes of CDK2 and cyclin H, cyclin I, ERH, hsReq*-1, and hsReq*-2, and derivatives, fragments and analogs thereof. The invention also provides nucleic acids encoding the hsReq*-1 and hsReq*-2, and proteins and derivatives, fragments and analogs thereof. Methods of screening the complexes for efficacy in treating and/or preventing certain diseases and disorders, particularly cancer, atherosclerosis and neurodegenerative disease are also provided.

    摘要: Methods are described for detecting protein-protein interactions, among two populations of proteins, each having a complexity of at least 100. Encoded proteins are fused either to the DNA-binding domain of a transcriptional activator or to the activation domain of a transcriptional activator. Two yeast strains, of the opposite mating type and carrying one type each of the fusion proteins are mated together. Productive interactions between the two halves due to protein-protein interactions lead to the reconstitution of the transcriptional activator, which in turn leads to the activation of a reporter gene containing a binding site for the DNA-binding domain. This analysis can be carried out for two or more populations of proteins. The differences in the genes encoding the proteins involved in the protein-protein interactions are characterized, thus leading to the identification of specific protein-protein interactions, and the genes encoding the interacting proteins, relevant to a particular tissue, stage or disease. Furthermore, inhibitors that interfere with these protein-protein interactions are identified by their ability to inactivate a reporter gene. The screening for such inhibitors can be in a multiplexed format where a set of inhibitors will be screened against a library of interactors. Further, information-processing methods and systems are described. These methods and systems pro vide for identification of the genes coding for detected interacting proteins, for assembling a unified database of protein-protein interaction data, and for processing this unified database to obtain protein interaction domain and protein pathway information.
