Complete set of molecular interactions in a biological cell
In molecular biology, an interactome is the whole set of molecular interactions in a particular cell. The term specifically refers to physical interactions among molecules (such as those among proteins, also known as protein–protein interactions, PPIs; or between small molecules and proteins[1]) but can also describe sets of indirect interactions among genes (genetic interactions).
The word "interactome" was originally coined in 1999 by a group of French scientists headed by Bernard Jacq.[3] Mathematically, interactomes are generally displayed as graphs. though interactomes may be described as biological networks, they should not be confused with other networks such as neural networks or food webs.
