Analysis of the docking interaction between Sld2 and Clb5 in budding yeast

Abstract

The cell cycle of Saccharomyces cerevisiae is governed by cyclin dependent kinases (Cdks), which are activated by periodically synthesized and degraded cyclins. The substrate target-ing by a cyclin-Cdk complex is mediated by the active site on the Cdk and the cyclin docking pocket. Docking interactions between short linear motifs (SLiMs) in target proteins and cy-clin-dependent kinases are shown to be critical regulators of different cell cycle events. SLiMs function in almost every pathway due to their role in regulatory function and signal transduction.
