The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

"
Winged helix-like DNA-binding domain superfamily/Winged helix DNA-binding domain
".

FunFam 265143: Histone H1

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 5 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 GO:0003677
Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
2 P53551 (/IPI) P53551 (/IPI)
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).
2 P53551 (/IPI) P53551 (/IPI)
Chromatin DNA binding GO:0031490
Interacting selectively and non-covalently with DNA that is assembled into chromatin.
2 P53551 (/IMP) P53551 (/IMP)
Phosphate ion binding GO:0042301
Interacting selectively and non-covalently with phosphate.
2 P53551 (/IMP) P53551 (/IMP)
Supercoiled DNA binding GO:0097100
Interacting selectively and non-covalently with supercoiled DNA. For example, during replication and transcription, template DNA is negatively supercoiled in the receding downstream DNA and positively supercoiled in the approaching downstream DNA.

2 P53551 (/IMP) P53551 (/IMP)
Chromosome condensation GO:0030261
The progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells.

There are 6 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
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.
3 P53551 (/IDA) P53551 (/IDA) Q9P8F8 (/IDA)
Chromatin GO:0000785
The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome.
2 P53551 (/IMP) P53551 (/IMP)
Nuclear nucleosome GO:0000788
A complex comprised of DNA wound around a multisubunit core and associated proteins, which forms the primary packing unit of DNA in the nucleus into higher order structures.
2 P53551 (/IPI) P53551 (/IPI)
Nuclear chromatin GO:0000790
The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.
2 P53551 (/IDA) P53551 (/IDA)
Protein-DNA complex GO:0032993
A macromolecular complex containing both protein and DNA molecules.
2 P53551 (/IMP) P53551 (/IMP)
Condensed nuclear chromosome GO:0000794
A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct nuclear chromosome.
