Treatment	% Found at different phases
	G1	S	G2/M
A549	43	38	19
Vector	47	36	18
Plk3-A	33	36	32
Plk3K52R	38	35	28
A549 + taxol	35	39	26
Vector + taxol	34	35	30

^aParental A549 cells or A549 cells transfected with Plk3-A, Plk3^K52R, or the vector alone for 12 h were treated with or without taxol for an additional 4 h. The cells were then processed and stained with propidium iodide. Cell cycle distributions were analyzed by flow cytometry. Data were summarized from three independent experiments.
