ABSTRACT:
FIELD OF THE INVENTION
This invention relates to newly identified polypeptides and polynucleotides encoding such polypeptides, to their use in therapy and in identifying compounds which may be agonists, antagonists and/or inhibitors which are potentially useful in therapy, and to production of such polypeptides and polynucleotides.
BACKGROUND OF THE INVENTION
The drug discovery process is currently undergoing a fundamental revolution as it embraces ‘functional genomics’, that is, high throughput genome- or gene-based therapy. This approach as a means to identify genes and gene products as therapeutic targets is rapidly superceding earlier approaches based on ‘positional cloning’. A phenotype, that is a biological function or genetic disease, would be identified and this would then be tracked back to the responsible gene, based on its genetic map position.
Functional genomics relies heavily on high throughput sequencing technologies and the various tools of bioinformatics to identify gene sequences of potential interest from the many molecular biology databases now available. This is a continuing need to identify and characterise further genes and their related polypeptides/proteins, as targets for drug discovery.
SUMMARY OF THE INVENTION
The present invention relates to Patched-2, in particular Patched-2 polypeptides and Patched-2 polynucleotides, recombinant materials and methods for their production. In another aspect, the invention relates to methods for using such polypeptides and polynucleotides, including the treatment of particularly cancer, but also kidney diseases, cardiovascular diseases, stroke, inflammatory disorders, neurological disorders, including alzheimers disease and mood disorders; developmental disorders, including Ptosis, hereinafter referred to as “the Diseases”, amongst others. In a further aspect, the invention relates to methods for identifying agonists and antagonists/inhibitors using the materials provided by the invention, and treating conditions associated with Patched-2 imbalance with the identified compounds. In a still further aspect, the invention relates to diagnostic assays for detecting diseases associated with inappropriate Patched-2 activity or levels.
