  • quasi steady state on mRNA expression
  • all hypothesis applicable to sub-parts
• Inputs:
  • nb-gene-copies
• Outputs:
  • [Protein]
• Internal parameters:
  •  ???

CellML structure (CellML 1.1 spec)

• Component: ConstitutiveProteinExpression
• Units:
  • TBD
• Imports:
  • Components:
    • ConstituvePromoter_RBS_Coupled
    • Protein

• Variables:
  • time (public interface = in)
  • nbGeneCopies (public interface = in)
  • protein (public interface = out / init value = 0.)
• MathML

Comments

• No too sure how to connect the components together following the import
• Do I have to declare all the variables I need to use from the imported components ?
• How do I 'trigger' the dynamic behaviour of the sub-components ?
