FunFam 38: Transcriptional repressor

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 10 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
DNA-binding transcription repressor activity, RNA polymerase II-specific GO:0001227
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a RNA polymerase II-transcribed gene to repress or decrease transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.

The proximal promoter is in cis with and relatively close to the core promoter.
1 Q03833 (/IDA)
DNA-binding transcription activator activity, RNA polymerase II-specific GO:0001228
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a RNA polymerase II-transcribed gene to activate or increase transcription.
