Table 1. The results of log-linear analysis.

The following notations are used: PD – interaction between phosphorylation and disorder features; PI – phosphorylation and interface; DI – disorder and interface; PH – phosphorylation and homooligomer; IH – interface and homooligomer; DH – disorder and homooligomer. “T” is a residue type. Good models have p-values larger than 0.05. Here we used all residues but the models did not change their form if only solvent-accessible residues were considered. The exception is the model for all three residues (last row of the table) which, in case of solvent accessible residues, included only three interaction terms (PIH, DI, PD).

Model	Residue type	Pearson chi- square	Degrees of freedom	p-value
PD+PI+DI+PH+IH	Ser	3.83	6	0.70
PD+PI+DI+IH+DH+PH	Thr	3.43	5	0.64
PD + PI+ DI+ IH + DH	Tyr	7.16	6	0.31
DI+PDT+DTH+ITH+PIH	Ser+Thr+Tyr	9.98	20	0.97
