protein interaction networks

Protein interaction networks map out how proteins communicate within a cell, showing which proteins connect or work together to perform biological functions. Think of it like a social network, where proteins are people, and their connections represent collaborations or interactions. These networks help scientists understand complex processes like how cells grow, respond to signals, or fight diseases. By studying these interactions, researchers can identify critical proteins involved in health and disease, leading to targeted treatments and better understanding of life at the molecular level.
