P: phosphorylation, P state +/-: phosphorylated or phospho-mimic and dephosphorylated or phospho-deficient respectively, W: water conductance, I: ion conductance, T: trafficking and/or protein cycling, L: protein localisation, SDM: phosphorylation or dephosphorylation mimic by site-directed mutagenesis, Pharm.: phosphorylation changes by application of pharmacological agents (kinase inhibitors or kinase activators). A ↑ or ↓ in the water or ion conductance column indicates if there was an increase or decreased observed; NE: No effect on function reported.
