Pre-steady-state behavior in the oocyte maturation MAPK cascade model. (A) Schematic view of the MAPK cascade. The cascade consists of a MAPK kinase kinase (MAPKKK), a MAPK kinase (MAPKK), and a MAPK. In this model, the dual phosphorylations of MAPK and MAPKK occur by a two-step, distributive mechanism. (B–D) Simulation of the Huang & Ferrell model. MAPK-PP vs. time for three different inputs (B), normalized MAPK-PP versus E1,tot for the indicated times (C), and nH versus time (D). The inset in panel D shows early times.
