FunFam 8: Regulator of G-protein signaling 4

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
G-protein alpha-subunit binding GO:0001965
Interacting selectively and non-covalently with a G-protein alpha subunit. The alpha subunit binds a guanine nucleotide.
1 P49799 (/IDA)
G-protein alpha-subunit binding GO:0001965
Interacting selectively and non-covalently with a G-protein alpha subunit. The alpha subunit binds a guanine nucleotide.
1 P49799 (/IPI)
GTPase activator activity GO:0005096
Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
1 P49799 (/IC)
GTPase activator activity GO:0005096
Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
1 P49799 (/IMP)
GTPase activator activity GO:0005096
Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
1 P49798 (/TAS)
Calmodulin binding GO:0005516
Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
1 P49798 (/TAS)

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
Inactivation of MAPK activity GO:0000188
Any process that terminates the activity of the active enzyme MAP kinase.
1 P49798 (/TAS)
Regulation of G-protein coupled receptor protein signaling pathway GO:0008277
Any process that modulates the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity.
1 P49798 (/TAS)
Positive regulation of GTPase activity GO:0043547
Any process that activates or increases the activity of a GTPase.
1 P49799 (/IMP)
Negative regulation of G-protein coupled receptor protein signaling pathway GO:0045744
Any process that stops, prevents, or reduces the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity.
1 P49799 (/IMP)

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
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
2 P49798 (/IDA) P49799 (/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 P49798 (/IDA)
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 P49799 (/IDA)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 P49799 (/IDA)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 P49799 (/IDA)
Protein complex GO:0043234
A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
