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:

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

FunFam 797: RHO1 GDP-GTP exchange protein 1

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 3 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
Rho guanyl-nucleotide exchange factor activity GO:0005089
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.

Rho guanyl-nucleotide exchange factor activity GO:0005089
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
2 P53046 (/ISA) P53046 (/ISA)
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).

There are 11 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
Small GTPase mediated signal transduction GO:0007264
Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.
2 P53046 (/IGI) P53046 (/IGI)
Fungal-type cell wall biogenesis GO:0009272
A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a fungal-type cell wall. The fungal-type cell wall contains beta-glucan and may contain chitin.
2 Q9UTR5 (/IGI) Q9Y7U6 (/IGI)
Actin cortical patch localization GO:0051666
Any process in which actin cortical patches are transported to, or maintained in, a specific location. An actin cortical patch is a discrete actin-containing structure found just beneath the plasma membrane in fungal cells.
2 Q9UTR5 (/IMP) Q9Y7U6 (/IMP)
Activation of GTPase activity GO:0090630
Any process that initiates the activity of an inactive GTPase through the replacement of GDP by GTP.
2 P53046 (/IGI) P53046 (/IGI)
Regulation of cell shape GO:0008360
Any process that modulates the surface configuration of a cell.
1 Q9Y7U6 (/IGI)
Ascospore wall assembly GO:0030476
The aggregation, arrangement and bonding together of a set of components to form an ascospore wall. During sporulation in Ascomycota, each ascospore nucleus becomes surrounded by a specialized spore wall, formed by deposition of spore wall components in the lumenal space between the outer and inner leaflets of the prospore membrane. An example of this process is found in Saccharomyces cerevisiae.
1 Q9UTR5 (/IMP)
Negative regulation of protein export from nucleus GO:0046826
Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of proteins from the nucleus into the cytoplasm.
1 Q9Y7U6 (/IC)
Positive regulation of bipolar cell growth GO:0051518
Any process that activates or increases the frequency, rate or extent of bipolar cell growth, polarized growth from both ends of a cell.
1 Q9Y7U6 (/IMP)
Regulation of ascospore wall beta-glucan biosynthetic process GO:0060622
Any process that modulates the rate, frequency or extent of ascospore wall beta-glucan biosynthetic process, the chemical reactions and pathways resulting in the formation of beta-glucans, compounds composed of glucose residues linked by beta-D-glucosidic bonds, found in the walls of ascospores.
1 Q9UTR5 (/IMP)
Regulation of cell wall (1->3)-beta-D-glucan biosynthetic process GO:0090334
Any process that modulates the rate, frequency, or extent of the chemical reactions and pathways resulting in the formation of (1->3)-beta-D-glucans, compounds composed of glucose residues linked by (1->3)-beta-D-glucosidic bonds, found in the walls of cells.
1 Q9Y7U6 (/IGI)
Regulation of cell wall organization or biogenesis GO:1903338
Any process that modulates the frequency, rate or extent of cell wall organization or biogenesis.
1 Q9Y7U6 (/EXP)

GO Term Annotations Evidence
Division septum GO:0000935
A cell septum which forms as part of the division site and functions in the compartmentalization of a cell into two daughter cells at division. A division septum spans a cell and does not allow exchange of organelles or cytoplasm between compartments.
2 Q9UTR5 (/IDA) Q9Y7U6 (/IDA)
Intracellular GO:0005622
The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
2 P53046 (/IDA) P53046 (/IDA)
Cell cortex of cell tip GO:0051285
The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.

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.

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.

Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 Q9UTR5 (/HDA)
Cell septum GO:0030428
A structure composed of peptidoglycan and often chitin in addition to other materials. It usually forms perpendicular to the long axis of a cell or hypha and grows centripetally from the cell wall to the center of the cell and often functions in the compartmentalization of a cell into two daughter cells.
