Interaction map

Definition

An interaction map is a visual representation that illustrates the complex network of interactions between proteins in a biological system. These maps help in understanding how proteins communicate with each other, which is crucial for elucidating cellular functions and biological pathways. By identifying and mapping these interactions, researchers can predict potential roles of proteins, discover new biological insights, and develop therapeutic strategies.
