a. Experimental plan. Both Seckel and WT cells were synchronized at G0 by serum starvation for 96 hrs. This treatment causes Seckel and WT cells to have equivalent cilia length allowing us to estimate the rate of cilia disassembly (see below and Appendix Fig. S2a).b, Dynamic CPAP localization during cilium disassembly and cell cycle re-entry. Cep152 levels remain unchanged. Arl13b (green) or acetylated α-tubulin (magenta) marks the cilium. n> 100 cells. Bar diagrams at right shows semi quantitative intensity measurements. Error bars are ± SD.
