From: The capacity for multistability in small gene regulatory networks
Two-component reciprocal repression. A reciprocal repression subnetwork consists of pair of genes (X1 and X2) in which each gene's product blocks transcription of the other gene, either as a monomer (X i + P j ⇌ X j P j for i ≠j) or a dimer (P i + P I ⇌ P i P i and X i + P j P j ⇌ X i P j P j for i ≠j). Basal protein production (X i → X i + P i ) and protein degradation (P i → ∅) are also included in specification of the subnetwork.
