Abstract
Protein kinase mutant and wild-type genes encoding polypeptides of the class heretofore designated "casein kinase I" and useful in screening compositions which may affect DNA double-strand break repair activity are disclosed. Also disclosed are methods using the polynucleotides in cell-proliferative disorders.
Claims1
A method of treating a disorder associated with abnormal expression of an HRR25-like protein comprising administering, to a subject with the disorder, a therapeutically effective amount of a composition which modulates the activity of the HRR25-like protein, said HRR25-like protein possessing greater than 35% amino acid sequence homology to the S. cerevisiae HRR25 protein kinase of SEQ ID NO:
- 2 in the protein kinase catalytic domain comprising amino acid residues 1 through 287 thereof, and wherein said HRR25-like protein:
- a) possesses protein kinase activity;
- b) promotes normal mitotic recombination;
- and
- c) promotes repair of a DNA strand break occurring at an HO endonuclease site.
