Biogrid

Definition

Biogrid is a comprehensive database that collects and organizes protein-protein interaction data from various organisms. It serves as a valuable resource for researchers to understand how proteins interact within biological systems, which is essential for deciphering cellular functions and signaling pathways. By cataloging these interactions, Biogrid helps researchers identify potential drug targets and explore the molecular mechanisms of diseases.
