Class PsiECAff

java.lang.Object
  extended byaffectors.Affector
      extended byaffectors.PsiECAff
All Implemented Interfaces:
java.lang.Cloneable

public class PsiECAff
extends Affector

This is similar to the Psi function except the inhibitor is in a neighboring cell from the one that contains the target Node. The input node used is from the neighboring cells. Use this version only for membrane-bound components, and only when the interaction in which it takes part is an interaction across a membrane (i.e. I have used it to repress heterodimerizations between ligand and receptor).

Formula
dnodex/dt = 1 - (NODEY ^ nu) / (K ^ nu + NODEY ^ nu)

Parameters

Affecting Node [NODEY] Usually an inhibitor Node. Will come from the face of a cell opposite to nodex's cell.
Half-maximal inhibition level [K_NODEYnodex] The concentration of inhibitor at which transcription is reduced by half.
Cooperativity [nu_NODEYnodex] The non-linearity of the inhibiting function. The higher the value, the sharper the curves in the S-shaped inhibition function.

Usage
&nodex

&PsiECAff NODEY K_NODEYnodex nu_NODEYnodex
