MODEL STATUS :  This model conforms to the CellML 1.0 Specification released on
10th August 2001, and the CellML Metadata 1.0 Specification released on 16th
January, 2002.

DESCRIPTION :  This file contains a CellML description of the mitogen-activated
protein kinase (MAPK) cascade.  It is based on the mathematical model published
by Huang and Ferrell in 1996.  

CHANGES:  
  24/10/2001 - CML - Made changes to some of the metadata, bringing them up to
                     date with the most recent working draft (26th September) of
                     the Metadata specification.
  22/01/2002 - AAC - Updated metadata to conform to the 16/1/02 CellML Metadata
                     1.0 Specification.
  22/07/2002 - CML - Added more metadata.
  09/04/2003 - AAC - Added publication date information.

<title>Model Structure</title>

<para>
The mitogen-activated protein kinase (MAPK) cascade is a series of three protein kinases.  Although the biological responses associated with this signalling pathway are diverse, the structure of the MAPK cascade is highly conserved between organisms (see <xref linkend="fig_pathway_diagram"/> below).  The cascade relays signals from the plasma membrane to targets in the cytoplasm and nucleus, often with the affect of amplifying the signal.
</para>

<para>
This model is based on Chi-Ying Huang and James Ferrell's mathematical model of the MAPK cascade, which they describe as a series of phosphorylation and dephosphorylation reactions (1996).  Ordinary differential equations (ODEs) describe sequential phosphorylation by kinases and dephosphorylation by phosphatases.  The ODEs are derived from the general description of enzymatic reactions based on Michaelis-Menten kinetics.

<para>
In CellML, models are thought of as connected networks of discrete components. These components may correspond to physiologically separated regions or chemically distinct objects, or may be useful modelling abstractions. The CellML rendering of the MAPK cascade model is shown in  <xref linkend="fig_cellml_rendering"/> (the different shapes in the diagram are explained in the <ulink url="${HTML_EXMPL_GRAPHICAL_NOTATION}">notation guide</ulink>).  The action of a catalyst on a reaction is represented by dashed lines.

          This is the CellML description of Huang and Ferrell's mathematical    
          model of the mitogen-activated protein kinase (MAPK) cascade (1996).  
          This signalling pathway involves a series of three, highly conserved  
          protein kinases which are associated with a diverse array of          
          biological responses.
