Abstract excerpt
Cyclin D1 regulates G1 cell-cycle progression and is aberrantly expressed in carcinogenesis. Proteasomal degradation of cyclin D1 was highlighted as a cancer chemopreventive mechanism. To understand this mechanism better, residues responsible for degradation and ubiquitination of cyclin D1 were investigated. Eighteen lysines in cyclin D1 had single, double or multiple mutations engineered before transfection into...
