abstract：:Two cDNAs encoding casein kinase-1 have been isolated from a yeast cDNA library and termed CKI1 and CKI2. Each clone encodes a protein of approximately 62,000 Da containing a highly conserved protein kinase domain surrounded by variable amino- and carboxy-terminal domains. The proteins also contain two conserved carbo...
