FunFam 116: Transcription factor 20 (AR1)

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 12 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
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
3 Q7Z5J4 (/IPI) Q9UGU0 (/IPI) Q9UGU0 (/IPI)
RNA polymerase II proximal promoter sequence-specific DNA binding GO:0000978
Interacting selectively and non-covalently with a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in the proximal promoter of a gene transcribed by RNA polymerase II. The proximal promoter is in cis with and relatively close to the core promoter.
2 Q66JM6 (/IDA) Q9EPQ8 (/IDA)
DNA binding GO:0003677
Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
2 Q9UGU0 (/NAS) Q9UGU0 (/NAS)
Transcription coactivator activity GO:0003713
A protein or a member of a complex that interacts specifically and non-covalently with a DNA-bound DNA-binding transcription factor to activate the transcription of specific genes. Coactivators often act by altering chromatin structure and modifications. For example, one class of transcription coregulators modifies chromatin structure through covalent modification of histones. A second ATP-dependent class modifies the conformation of chromatin. Another type of coregulator activity is the bridging of a DNA-binding transcription factor to the basal transcription machinery. The Mediator complex, which bridges transcription factors and RNA polymerase, is also a transcription coactivator.
2 Q9UGU0 (/NAS) Q9UGU0 (/NAS)
RNA binding GO:0003723
Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
2 Q9UGU0 (/HDA) Q9UGU0 (/HDA)
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. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
1 Q9EPQ8 (/IC)
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. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
1 Q66JM6 (/IDA)
DNA-binding transcription factor activity GO:0003700
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 gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
1 Q9EPQ8 (/IDA)
Enhancer binding GO:0035326
Interacting selectively and non-covalently with an enhancer, a transcription regulatory region that is somewhat distal from the core promoter and which enhances transcription from that promoter.
1 Q7Z5J4 (/IDA)
Enhancer binding GO:0035326
Interacting selectively and non-covalently with an enhancer, a transcription regulatory region that is somewhat distal from the core promoter and which enhances transcription from that promoter.
1 Q61818 (/ISO)
Enhancer binding GO:0035326
Interacting selectively and non-covalently with an enhancer, a transcription regulatory region that is somewhat distal from the core promoter and which enhances transcription from that promoter.
1 Q61818 (/ISS)
Transcription regulatory region DNA binding GO:0044212
Interacting selectively and non-covalently with a DNA region that regulates the transcription of a region of DNA, which may be a gene, cistron, or operon. Binding may occur as a sequence specific interaction or as an interaction observed only once a factor has been recruited to the DNA by other factors.
