(C) Zwint‐1 levels do not change in Beclin‐1‐depleted cells. Cells were treated with nocodazole before fixation. On the right, magnified individual kinetochore pairs stained for Zwint‐1 (red) and CREST (green), and quantification of Zwint‐1 levels normalized to CREST signal from three independent experiments (error bars=s.d.).
