Pfam

Pfam is a comprehensive database that catalogs groups of related protein sequences called protein families. It helps scientists understand how proteins are structured and function by identifying common patterns, known as "domains," within different proteins. Think of Pfam as a detailed library that categorizes proteins based on shared features, enabling researchers to predict the role of new or unknown proteins by comparing them to known families. This tool is essential for studying biological processes, understanding diseases, and developing new medicines.
