Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

5 GO

Gene Ontology (GO)

5
  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • 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:0003690 Binding to double-stranded DNA.
  • GO:0045892 Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
  • 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.

1 records

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.
