Abstract

Exit from mitosis requires inactivation of mitotic cyclin-dependent kinases (CDKs). A key mechanism of CDK inactivation is ubiquitin-mediated cyclin proteolysis, which is triggered by the late mitotic activation of a ubiquitin ligase known as the anaphase-promoting complex (APC). Activation of the APC requires its association with substoichiometric activating subunits termed Cdc20 and Hct1 (also known as Cdh1). Here, we explore the molecular function and regulation of the APC regulatory subunit Hct1 in Saccharomyces cerevisiae.
