protein interaction network

A protein interaction network is a visual map showing how proteins within a cell connect and work together. Proteins are essential molecules that perform various functions, and they often cooperate by binding or interacting with each other. The network illustrates these relationships, highlighting how proteins communicate and coordinate to carry out biological processes like growth, repair, and immune response. Understanding these interactions helps scientists identify important proteins involved in health and disease, and how disrupting certain connections can lead to conditions like cancer or infections.
