UniProt

Definition

UniProt is a comprehensive protein sequence and functional information database that provides a centralized resource for protein data, enabling researchers to access detailed information about proteins, including their sequences, functions, structures, and roles in various biological processes. It is crucial for computational approaches to protein structure prediction, as it serves as a repository of annotated protein sequences that can be used for modeling and understanding protein functions.
