The results represent the mean ± SD of the 80 cells analysed in two independent experiments (40 cells in each experiments). The statistical significance of differences in parameters examined between SP-4 (wild-type) and fob1Δ, sfp1Δ with the one-way analysis of variance (ANOVA)

SP-4 (wild-type)	39.1 ± 15.5	67.6 ± 24.7	26.0 ± 36.2	90.1 ± 38.5
