SUV39H1 activity controls the tension between sister kinetochores.

Treatment	Distance (μm)a
Scramble/DMSO-treated	1.43 ± 0.18
SUV39H1 siRNA#1 (mis-aligned kinetochore)	1.18 ± 0.17
SUV39H1 siRNA#2 (mis-aligned kinetochore)	1.16 ± 0.19
Chaetocin (mis-aligned kinetochore)	1.19 ± 0.18
Chaetocin+hesperadin (mis-aligned kinetochore)	1.31 ± 0.23
SUV39H1 siRNA#1 + nocodazole treatment	1.01 ± 0.13

Data were obtained >150 kinetochore pairs in which kinetochores were in the same focal plane.
