FunFam 230: POU domain protein

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
RNA polymerase II regulatory region sequence-specific DNA binding GO:0000977
Interacting selectively and non-covalently with a specific sequence of DNA that is part of a regulatory region that controls the transcription of a gene or cistron by RNA polymerase II.
1 P13528 (/IDA)
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 P13528 (/IDA)
Single-stranded DNA binding GO:0003697
Interacting selectively and non-covalently with single-stranded DNA.
1 P55968 (/ISS)
Transcription factor binding GO:0008134
Interacting selectively and non-covalently with a transcription factor, a protein required to initiate or regulate transcription.
1 P13528 (/IPI)
Sequence-specific DNA binding GO:0043565
Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
1 P13528 (/IDA)
Sequence-specific DNA binding GO:0043565
Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.

There are 14 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
Heart development GO:0007507
The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
3 F1Q813 (/IGI) Q5KS49 (/IGI) Q7SZN6 (/IGI)
Mechanosensory behavior GO:0007638
Behavior that is dependent upon the sensation of a mechanical stimulus.
1 P13528 (/IMP)
Response to mechanical stimulus GO:0009612
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 a mechanical stimulus.
1 P13528 (/IMP)
Positive regulation of gene expression GO:0010628
Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
1 P55968 (/ISS)
Neuron projection development GO:0031175
The process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites).
1 P55968 (/ISS)
Positive regulation of osteoclast differentiation GO:0045672
Any process that activates or increases the frequency, rate or extent of osteoclast differentiation.
1 P55968 (/ISS)
Positive regulation of transcription by RNA polymerase II GO:0045944
Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
1 P13528 (/IDA)
Positive regulation of transcription by RNA polymerase II GO:0045944
Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
1 P13528 (/IMP)
Neuron development GO:0048666
The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.
1 P13528 (/IMP)
Regulation of DNA-binding transcription factor activity GO:0051090
Any process that modulates the frequency, rate or extent of the activity of a transcription factor, any factor involved in the initiation or regulation of transcription.
1 P55968 (/ISS)
Cellular response to cytokine stimulus GO:0071345
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cytokine stimulus.
1 P55968 (/ISS)
Cellular response to estradiol stimulus GO:0071392
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of stimulus by estradiol, a C18 steroid hormone hydroxylated at C3 and C17 that acts as a potent estrogen.
1 P55968 (/ISS)
Positive regulation of transcription from RNA polymerase II promoter involved in neuron fate specification GO:1904080
Any positive regulation of transcription from RNA polymerase II promoter that is involved in neuron fate specification.
1 P13528 (/IMP)
Positive regulation of transcription regulatory region DNA binding GO:2000679
Any process that activates or increases the frequency, rate or extent of transcription regulatory region DNA binding.

GO Term Annotations Evidence
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.
