Imported:YPM/Ste12 Kss1 pTpY factor
<modelParameter>Ste12_Kss1_pTpY_factor = </modelParameter>
This is the factor by which Kss1 phosphorylation on both T183 and Y185 alters its binding affinity for Ste12.
Kd_Ste12_Kss1pTpY = Ste12_Kss1_pTpY_factor * Kd_Ste12_Kss1
Ste12_Kss1_pTpY_factor > 1 means that phosphorylation of Kss1 on both T183 and Y185 decreases its binding affinity for Ste12.
