UniProt ID Identifier

What is a UniProt ID?

The UniProt ID is a unique identifier assigned to each protein in the UniProt (Universal Protein Resource) database, which provides comprehensive protein sequence and functional information.

Format

UniProt IDs have different formats depending on the database:
- UniProtKB/Swiss-Prot: Manual annotation (e.g., P12345)
- UniProtKB/TrEMBL: Automatic annotation (e.g., Q9XYZ1)

Purpose

• Standardization: Consistent protein identification
• Cross-referencing: Links to detailed protein information
• Data Integration: Combining proteomics data from different studies
