ID: Constitutive Promoter

• Description: Promoter with constant transcription rate at a given number of gene copies
• Hypothesis:
  • Constant and continuous transcription rate
  • Transcription rate depends on number of gene copies
  • unlimited resources for transcription (excess in polymerase ...)
  • No effect from activators or repressors
• Inputs:
  • nb-gene-copies
• Outputs:
  • PoPs
• Internal parameters:
  • transcription-rate (per gene copy)

CellML structure (CellML 1.1 spec)

• Component: ConstitutivePromoter
• Units:
  • TBD
• Variables:
  • nb-gene-copies (public interface = in / init value = 1.0)
  • transcription-rate (public interface = none / init value = XXX)
  • PoPs-OUT (public interface = out / init value = 0.)
• MathML
  • <amsmath>PoPs-OUT = transcription-rate*nb-genes-copies</amsmath>
