Abstract: The invention concerns RAC-PK and fragments thereof, as well as activators and inhibitors of RAC-PK for use as medicaments, particularly in the treatment of diseases concerned with abnormalities in processes modulated by insulin, such as cellular proliferation, insulin deficiency and/or excess blood sugar levels. Moreover, the invention provides RAC-PK for use in screening potential mimics or modulators thereof. A method for screening for agents capable of affecting the activity of GSK3 is also disclosed. The invention further provides a screening kit comprising the RAC-PK as an active principle, and a method for screening compounds which are candidate mimics or modulators of RAC-PK activity comprising detecting specific interactions between the candidate compounds and RAC-PK. There is also provided a process for activating RAC-PK comprising treatment thereof with a phosphatase inhibitor.

Abstract: The present invention relates to the diagnosis, prognosis or predisposition of developing cancer, especially lymphoma. The invention also relates to gene therapy and identification of potential new therapeutic agents for treating cancer such as lymphoma.

Abstract: This invention provides purified PKB Ser 473 kinase and methods of purifying it. The methods involve the use of several sequential steps, including subcellular fractionation to isolate a plasma membrane fraction and the use of gel filtration or chromatography that separates molecules according to their size or affinity.

Abstract: A human protein (designated Carboxy-terminal Modulating protein, CTMP) is described and is identified as having tumour suppressor properties. CTMP has been shown to interact with protein kinase B and inhibit protein kinase B activity, establishing its importance in the protein kinase B signalling pathway.

Abstract: Methods of treating disorders associated with the PKB signalling pathway, such as cancer, diabetes, and neurodegenerative disorders, are provided. The methods comprise modulating the activity of DNA-PK; this enzyme has been identified as having serine 473 kinase activity. Compositions comprising DNA-PK or modulators thereof are also provided for use in such methods.

Abstract: The present invention relates to the phosphorylated form of nuclear serine/threonine protein kinase, designated nuclear, Dbf2-related kinase (Ndr), and provides assays and materials for identifying modulators thereof. The invention relates to the fields of molecular biology, chemistry, pharmacology, and screening technology.
