UniProt

Definition

UniProt is a comprehensive, freely accessible database of protein sequence and functional information. It plays a crucial role in bioinformatics and genomics by providing researchers with extensive data on protein sequences, structures, functions, and interactions, thereby aiding in the understanding of biological processes and systems.

5 Must Know Facts For Your Next Test

1. UniProt is divided into three main components: UniProtKB (the knowledge base), UniParc (the archive of protein sequences), and UniRef (the clustered sets of sequences).
2. UniProt provides detailed annotations on proteins, including their functions, interactions, structures, and post-translational modifications.
3. The database is continuously updated with new protein data derived from both experimental research and computational predictions.
4. UniProt serves as a vital resource for researchers studying protein functions in various organisms, supporting fields like drug discovery and systems biology.
5. Data from UniProt is widely used in various applications, including molecular biology research, clinical studies, and teaching in bioinformatics courses.

Review Questions
