An isolated c-Fos regulating kinase polypeptide (FRK) characterized by having a molecular weight of 88 kD as determined by reducing SDS-PAGE, having threonine and serine kinase activity, phosphorylating the c-Fos activation domain and polynucleotide sequences and method of detection of FRK are provided herein. Also described are methods for identifying compositions which affect FRK activity, thereby affecting c-Fos activation and subsequent activation of genes associated with AP-1 sites. |
