. The spindle checkpoint functions of Mad3 and Mad2 depend on a Mad3 KEN box-mediated interaction with Cdc20-anaphase-promoting complex (APC/C). J Biol Chem. 2008;283:23039-47 pubmed publisher
..Our findings demonstrate that this Mad3 KEN box is a critical mediator of Cdc20-APC/C inhibition, without which neither Mad3 nor Mad2 can associate with the APC/C or inhibit anaphase onset. ..

..Gene cloning established that these mutants were defective in either the subunits (Cut9, Cut23, Cut20 or Apc10) of APC (anaphase promoting complex)/cyclosome or Cut8, a regulator for 26S proteasome ..

..Phosphorylation of Hcn1 occurs at a single Cdk1 site in vitro and in vivo. Mutation of this site to alanine, but not aspartic acid, compromises APC/C function and leads to a specific defect in the completion of cell division. ..
Kimata Y, Kitamura K, Fenner N, Yamano H. Mes1 controls the meiosis I to meiosis II transition by distinctly regulating the anaphase-promoting complex/cyclosome coactivators Fzr1/Mfr1 and Slp1 in fission yeast. Mol Biol Cell. 2011;22:1486-94 pubmed publisher
..Thus Mes1 interacts with two coactivators in a different way to control the activity of the APC/C required for the meiosis I/meiosis II transition...

..We propose that each of the two E2 enzymes is responsible for collaborating with APC/C for a specific set of substrates, and that Ubc11 is responsible for regulating Slp1 with APC/C for silencing the SAC. ..
