Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
MAPK_MKP1_ oscillation	9	Network	Shared_Object_MAPK_MKP1_oscillation,  PKC,  MAPK,   PLA2,  Ras
This model relates to figure 5 in Bhalla US, Iyengar R. Chaos (2001) 11(1):221-226. It includes the model used for figures 2-4 and also has MKP-1 induction by MAPK activity in the synapse. PP2A is set to 0.16 uM and MKP synthesis is varied from 5x to 40 x basal to get a range of interesting behaviours.
