    Cdk1 phoshorylation of Cdc20 is required for an efficient mitotic arrest in response to microtubule poisons. (A) Live cell imaging of Hela cells depleted of endogenous Cdc20 and transiently expressing untagged Cdc20 WT, 3DD, or 3AA in the presence of nocadazole (30 ng/ml). Percentage of cells that exit mitosis during the course of imaging from three independent experiments (mean and SD indicated). (B) As in A, time from nuclear envelope breakdown (NEBD) to mitotic exit or end of filming from three independent experiments (each dot represents a single cell, red line indicates mean and SD, n values are shown in the graph and represent single cells analyzed per condition; statistical analysis with Mann-Whitney test; ****P > 0.0001). (C) Live cell imaging of stable cell lines that were depleted of endogenous Cdc20 and expressing indicated YFP-tagged Cdc20 proteins in the presence of nocodazole (30 ng/ml). The R132A mutation prevents <t>Mad2</t> binding, while the 4A mutations prevent BubR1 binding. Time from NEBD to mitotic exit (each dot represents a single cell, red line indicates mean and standard deviation, n values are shown in the graph and represent single cells analyzed per condition, statistical analysis with Mann-Whitney test; ****P > 0.0001). (D) Model: MCC-bound BubR1 is preferentially dephosphorylated by PP2A-B56, whereas free Cdc20 is phosphorylated by Cdk1.

Bar is 10μm. b, The percentage of cells that complete mitosis normally or with a delay from prophase to anaphase (>50 min) or that undergo apoptosis during prometaphase was quantified (n = 50). c, The percentage of cells that undergo normal mitosis, become multinucleated or die during mitosis was quantified (n=50). d, HeLa cells were treated with the indicated siRNAs for 48 h and analyzed by immunofluorescence microscopy for <t>MAD2</t> and kinetochores. The percentage of prometaphase and metaphase cells that contain one or more MAD2 positive kinetochores was quantified (n = 30). Example images are shown in Suppl. Fig. 1c. e, HeLa cells expressing H2B-mRFP were treated with the indicated mixtures of siRNAs for 48 h and analyzed by live-cell microscopy.

    Cdk1 phoshorylation of Cdc20 is required for an efficient mitotic arrest in response to microtubule poisons. (A) Live cell imaging of Hela cells depleted of endogenous Cdc20 and transiently expressing untagged Cdc20 WT, 3DD, or 3AA in the presence of nocadazole (30 ng/ml). Percentage of cells that exit mitosis during the course of imaging from three independent experiments (mean and SD indicated). (B) As in A, time from nuclear envelope breakdown (NEBD) to mitotic exit or end of filming from three independent experiments (each dot represents a single cell, red line indicates mean and SD, n values are shown in the graph and represent single cells analyzed per condition; statistical analysis with Mann-Whitney test; ****P > 0.0001). (C) Live cell imaging of stable cell lines that were depleted of endogenous Cdc20 and expressing indicated YFP-tagged Cdc20 proteins in the presence of nocodazole (30 ng/ml). The R132A mutation prevents Mad2 binding, while the 4A mutations prevent BubR1 binding. Time from NEBD to mitotic exit (each dot represents a single cell, red line indicates mean and standard deviation, n values are shown in the graph and represent single cells analyzed per condition, statistical analysis with Mann-Whitney test; ****P > 0.0001). (D) Model: MCC-bound BubR1 is preferentially dephosphorylated by PP2A-B56, whereas free Cdc20 is phosphorylated by Cdk1.

    a, HeLa cells expressing H2B-mRFP were treated with the indicated siRNAs for 48 h and analyzed by live-cell microscopy. Stars indicate misaligned and lagging chromosomes. Bar is 10μm. b, The percentage of cells that complete mitosis normally or with a delay from prophase to anaphase (>50 min) or that undergo apoptosis during prometaphase was quantified (n = 50). c, The percentage of cells that undergo normal mitosis, become multinucleated or die during mitosis was quantified (n=50). d, HeLa cells were treated with the indicated siRNAs for 48 h and analyzed by immunofluorescence microscopy for MAD2 and kinetochores. The percentage of prometaphase and metaphase cells that contain one or more MAD2 positive kinetochores was quantified (n = 30). Example images are shown in Suppl. Fig. 1c. e, HeLa cells expressing H2B-mRFP were treated with the indicated mixtures of siRNAs for 48 h and analyzed by live-cell microscopy. The percentage of cells that die in prometaphase was quantified (n = 50). b-d, Bars represent the mean of three independent experiments. Error bars indicate +/-s.d.
