FunFam 73: MAX dimerization protein 3

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 4 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 Q80US8 (/IPI) Q9BW11 (/IPI) Q9BW11 (/IPI)
DNA-binding transcription factor activity, RNA polymerase II-specific GO:0000981
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 modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
2 Q9BW11 (/ISA) Q9BW11 (/ISA)
DNA-binding transcription factor activity, RNA polymerase II-specific GO:0000981
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 modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
2 Q9BW11 (/ISM) Q9BW11 (/ISM)
DNA-binding transcription factor activity, RNA polymerase II-specific GO:0000981
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 modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.

There are 2 GO terms relating to "biological process"

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
Negative regulation of transcription by RNA polymerase II GO:0000122
Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.
1 Q80US8 (/IDA)
Negative regulation of transcription, DNA-templated GO:0045892
Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
1 Q80US8 (/IGI)

There are 1 GO terms relating to "cellular component"

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
RNA polymerase II transcription factor complex GO:0090575
A transcription factor complex that acts at a regulatory region of a gene transcribed by RNA polymerase II.
