Figure 1From: Analysis of the role of Ser1/Ser2/Thr9 phosphorylation on myosin II assembly and function in live cellsRLC Ser1 phosphorylation is elevated in mitotic cells and localizes to the contractile ring. (A) HeLa and primary human keratinocytes (PHK) under normal growth conditions were fixed and immunostained for RLC Ser1-P (green) and stained for actin (red). (B) RLC Ser1-P is specifically enhanced in the contractile ring of dividing cells.Back to article page
