The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Helix-loop-helix DNA-binding domain
".
FunFam 50: Basic helix-loop-helix transcription factor
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 2 GO terms relating to "molecular function"

|
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.

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).

Regulation of transcription, DNA-templated GO:0006355
Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

Guard cell differentiation GO:0010052
The process in which a guard mother cell acquires the specialized features of a guard cell.

|
Guard cell fate commitment GO:0010377
The process in which the developmental fate of a cell becomes restricted such that it will develop into a stomatal guard cell. Guard cells are located in the leaf epidermis and pairwise surround stomatal pores, which allow CO2 influx for photosynthetic carbon fixation and water loss via transpiration to the atmosphere.

Guard mother cell differentiation GO:0010444
The process in which a meristemoid acquires the specialized features of a guard mother cell.

Negative regulation of histone H3-K27 methylation GO:0061086
Any process that decreases the rate, frequency, or extent of histone H3-K27 methylation. Histone H3-K27 methylation is the modification of histone H3 by addition of a methyl group to lysine at position 27 of the histone.

Response to low humidity GO:0090547
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of low humidity stimulus, reduced moisture in the atmosphere.

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
