FunFam 22: High mobility group B protein 15

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 7 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 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.
5 Q9LG02 (/ISS) Q9LTT3 (/ISS) Q9MAT6 (/ISS) Q9MAT6 (/ISS) Q9SGS2 (/ISS)
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 Q9LG02 (/IPI) Q9LTT3 (/IPI) Q9SGS2 (/IPI)
Four-way junction DNA binding GO:0000400
Interacting selectively and non-covalently with DNA containing four-way junctions, also known as Holliday junctions, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices.
2 Q9MAT6 (/IDA) Q9MAT6 (/IDA)
Transcription factor binding GO:0008134
Interacting selectively and non-covalently with a transcription factor, a protein required to initiate or regulate transcription.
2 Q9MAT6 (/IPI) Q9MAT6 (/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.
2 Q9MAT6 (/IPI) Q9MAT6 (/IPI)
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.
2 Q9MAT6 (/IPI) Q9MAT6 (/IPI)
DNA binding GO:0003677
Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
1 Q9SGS2 (/IDA)

There are 6 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
Regulation of transcription, DNA-templated GO:0006355
Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
3 Q9MAT6 (/TAS) Q9MAT6 (/TAS) Q9SGS2 (/TAS)
Pollen germination GO:0009846
The physiological and developmental changes that occur in a heterosporous plant pollen grain, beginning with hydration and terminating with the emergence of the pollen tube through the aperture.
2 Q9MAT6 (/IMP) Q9MAT6 (/IMP)
Pollen tube growth GO:0009860
Growth of pollen via tip extension of the intine wall.
2 Q9MAT6 (/IMP) Q9MAT6 (/IMP)
Glucosinolate metabolic process GO:0019760
The chemical reactions and pathways involving glucosinolates, substituted thioglucosides found in rapeseed products and related cruciferae. They are metabolized to a variety of toxic products which are most likely the cause of hepatocytic necrosis in animals and humans.
2 Q9MAT6 (/IMP) Q9MAT6 (/IMP)
Karyogamy GO:0000741
The creation of a single nucleus from multiple nuclei as a result of fusing the lipid bilayers that surround each nuclei.
1 Q9SGS2 (/IMP)
Polar nucleus fusion GO:0010197
The merging of the polar nuclei, the two nuclei contained within the same cell that are created from the mitotic division of the megaspore during angiosperm reproduction. Polar nuclear fusion takes place in the ovule, forming in the fusion nucleus and giving rise to the endosperm when fertilized.
1 Q9SGS2 (/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.
GO Term Annotations Evidence
Pollen tube GO:0090406
A tubular cell projection that is part of a pollen tube cell and extends from a pollen grain.
2 Q9MAT6 (/IDA) Q9MAT6 (/IDA)
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.
1 Q9SGS2 (/IDA)
Chloroplast GO:0009507
A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
