Important interacting proteins
Bhattacharyya M, Chakrabarti S. Identification of important interacting proteins (IIPs) in Plasmodium falciparum using large-scale interaction network analysis and in-silico knock-out studies. Malar J. 2015 Feb 8;14:70
Shown are the expression pattern of interacting partners (protein 1 & protein 2) and the expression of both proteins in 4 intraerythrocytic  stages: merozoite (M), ring stage(R), trophozoite (T), and schizont (S). Each stage is denoted by a color. Hence a box is colored if the protein is present in that stage and the box is white if it is absent. At least one partner of the interaction is present in any one stage only. Hence the interaction cannot happen in other stages even if the other partner is present in other stages. That is why when you look at the ring stage specific file you will see any one of the protein 1 or proein 2 is expressed uniquely in ring stage and the other one could be present in other stages also. This observation basically indicates a dynamic pattern of interaction in which a single protein interacts with different proteins in different stages. The colored PfIDs are important interacting proteins (see original article)
