Answer: Sic1 in yeast (Cdk inhibitor p27). 2) DNA replication at each origin occurs only once during the cell cycle … WebSic1 is a protein in the budding yeast "Saccharomyces cerevisiae". It is a cyclin-dependent kinase (Cdk) inhibitor and is an important regulator of the cell cycle where one of its … Skp2 binds p27 Kip1 only when two conditions are met: p27 Kip1 is phosphorylated by E/A/CKD2 and bound to Cks1. As a consequence of binding Skp2, ... SCF-Fbw7 targets Sic1—when at least six out of nine possible sites are phosphorylated—and Swi5 for degradation. See more Skp, Cullin, F-box containing complex (or SCF complex) is a multi-protein E3 ubiquitin ligase complex that catalyzes the ubiquitination of proteins destined for 26S proteasomal degradation.
