YB-1 is required for formation of the cleavage furrow. Examples of synchronized A549 cells enriched for cytokinesis, immunostained with antibodies against (from left to right) α-tubulin (cyan), YB-1 (red), merge of α-tubulin and YB-1, β-actin (yellow), merge of β-actin and YB-1, AURKB (green) followed by a merged image of all three. Images were acquired using a 60× oil-immersion objective.
