Abstract
This invention relates to a class of checkpoint genes and their polypeptide products which control progression through the cell cycle in eukaryotic cells. In particular this invention relates to Schizosaccharomyces pombe rad3 gene, to its human homologue (ATR) and to their encoded proteins. The invention further relates to assay methods for selecting compounds which modulate the activity of the polypeptide products of these checkpoint genes and the use of the selected compounds in anticancer therapy.
Claims6
A purified and isolated polynucleotide encoding an ATR polypeptide that has lipid kinase activity, said polynucleotide selected from the group consisting of:
- (a) a polynucleotide encoding the amino acid sequence set out in SEQ ID NO:
- 2,
- (b) a polynucleotide encoding the amino acid sequence set out in SEQ ID NO:
- 4, and
- (c) a polynucleotide which hybridizes to the complement of the polynucleotide of (a) or (b) under conditions including a final wash at 55° C.
