  • Title: A kinase-independent function of Cks1 and Cdk1 in regulation of transcription.
    Author: Yu VP, Baskerville C, Grünenfelder B, Reed SI.
    Journal: Mol Cell; 2005 Jan 07; 17(1):145-51. PubMed ID: 15629725.
    Abstract:
    We describe a function in transcription for the Saccharomyces cerevisiae cell cycle regulatory cyclin-dependent kinase Cdc28 (Cdk1) and its interacting protein, Cks1. The Cks1/Cdc28 complex is recruited to multiple coding regions in the genome and is necessary for efficient expression of a significant subset of genes. This transcriptional role is mediated through a requirement of Cdc28/Cks1 for recruiting proteasomes to coding regions. However, it is independent of the protein kinase activity of Cdc28. In the absence of Cks1, neither Cdc28 nor the proteasome can be recruited. Consequently, there is a failure to maintain efficient transcription.
