Model of genetic regulation with a positive autoregulatory feedback loop.

(a) The transcription factor activator (TF-A) activates transcription with a maximal rate kf when phosphorylated (P) and binds as a dimer to specific responsive-element DNA sequences(TF-REs). TF-A is decomposed with rate kd and synthesized with rate Rbas. (b) The bistable potential. The parameter values are kf = 7.5 min−1, Kd = 10, kd = 1 min−1 and Rbas = 0.1 min−1. The stable states are x− ≈ 0.1089 nM and x+ ≈ 5.9467 nM and the unstable steady state is xu ≈ 1.5445 nM.
