Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
EGFR_Signaling_ pathway	52	Pathway	EGFR
This model is based on the model and parameters published in paper: Quantification of Short Term Signaling by the EGFR Kholodenko et al, The J Biol Chem. , Vol 274, No. 42, Issue of October 15, pp. 30169 - 30181, 1999. Note: There are a few small ambiguities in the paper about initial conditions employed for obtaining the results. Thanks to Dr. Kholodenko for clarifying those ambiguities and providing the values used in the simulations:[G-S]=33.04579, [Grb]=51.95431, [SOS]=0.95421.

PLCrP acting as a Substrate in a reaction in EGFR_Signaling_pathway Network

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
