Schematic diagram of simplified model of β-catenin non-GSK3β phosphorylation and degradation reaction steps. The reaction rate constants of these reaction steps are denoted kβ/kβ' (forward/backward reaction) and kβdeg, respectively (see text for detailed description). Numbering of reaction steps 12 and 13 is the same as in the original Lee-Heinrich model [2].
