The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

"
Metal Binding Protein, Guanine Nucleotide Exchange Factor; Chain A

FunFam 5: Guanine nucleotide exchange factor MSS4

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 4 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
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
4 B0G120 (/ISS) Q9U1X4 (/ISS) Q9VLP3 (/ISS) Q9VLP3 (/ISS)
Rab guanyl-nucleotide exchange factor activity GO:0017112
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rab 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 Q9VLP3 (/IGI) Q9VLP3 (/IGI)
Guanyl-nucleotide exchange factor activity GO:0005085
Stimulates the exchange of guanyl nucleotides associated with a GTPase. 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.
1 O43057 (/ISO)
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
1 O43057 (/ISO)

There are 4 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
Positive regulation of GTPase activity GO:0043547
Any process that activates or increases the activity of a GTPase.
2 Q9VLP3 (/IGI) Q9VLP3 (/IGI)
Polarized secretion of basement membrane proteins in epithelium GO:0061865
The basement membrane constituent secretion in which there is a restriction or targeting of basement membrane proteins for controlled release on the basal side of polarized epithelium.
2 Q9VLP3 (/IMP) Q9VLP3 (/IMP)
Post-Golgi vesicle-mediated transport GO:0006892
The directed movement of substances from the Golgi to other parts of the cell, including organelles and the plasma membrane, mediated by small transport vesicles.
1 O43057 (/ISO)
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.
1 O43057 (/IC)

There are 3 GO terms relating to "cellular component"

GO Term Annotations Evidence
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
2 Q9VLP3 (/ISS) Q9VLP3 (/ISS)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
2 Q9VLP3 (/ISS) Q9VLP3 (/ISS)
Basal cortex GO:0045180
The region that lies just beneath the plasma membrane on the basal edge of a cell.
