Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Gene Ontology (GO)
3- GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
- GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
- GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

Ligand evidence
Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.
Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.
No PDB structure with a co-crystallized ligand found for this exact protein.
Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
