FunFam 84: class A basic helix-loop-helix protein 9

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 6 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 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.
1 Q7RTU4 (/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.
1 Q7RTU4 (/ISM)
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).
1 Q7RTU4 (/IPI)
Protein heterodimerization activity GO:0046982
Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
1 Q7RTU4 (/IDA)
Protein heterodimerization activity GO:0046982
Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
1 Q5RJB0 (/ISO)
Protein heterodimerization activity GO:0046982
Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
1 Q5RJB0 (/ISS)

There are 1 GO terms relating to "biological process"

GO Term Annotations Evidence
Pectoral fin development GO:0033339
The process whose specific outcome is the progression of the pectoral fin over time, from its formation to the mature structure.
1 A3KNX5 (/IMP)

There are 3 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.
