Relative concentrations of Myo2p at contractile rings as a function of myo2 copy number

Strain	YFP-Myo2p (μM)a
1xYFP-myo2	20 ± 6.4b
2xYFP-myo2	45 ± 13.7

^a Local concentration (±SD) of YFP-Myo2p at mature, nonconstricting contractile rings based on fluorescence intensity measurements (relative to those of 1xYFP-myo2 haploid strains) presented in Figure 1. n = 60 rings.

^b Final average fluorescence intensity values for YFP-Myo2p in rings of the 1xYFP-myo2 strain were set to 20 μM, the established local concentration of Myo2p in nonconstricting rings in YFP-myo2 cells (Wu and Pollard, 2005).
