FunFam 6: Guanine nucleotide exchange factor SPIKE 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 2 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.
1 Q8SAB7 (/IDA)
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).
1 Q8SAB7 (/IPI)

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 actin polymerization or depolymerization GO:0008064
Any process that modulates the frequency, rate or extent of the assembly or disassembly of actin filaments by the addition or removal of actin monomers from a filament.
1 Q8SAB7 (/IMP)
Regulation of cell shape GO:0008360
Any process that modulates the surface configuration of a cell.
1 Q8SAB7 (/IMP)
Positive gravitropism GO:0009958
The orientation of plant parts towards gravity.
1 Q8SAB7 (/IMP)
Regulation of auxin mediated signaling pathway GO:0010928
Any process that modulates the rate, frequency or extent of auxin mediated signaling pathway. Auxin mediated signaling pathway is the series of molecular signals generated in response to detection of auxin.
1 Q8SAB7 (/IMP)
Vesicle-mediated transport GO:0016192
A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
1 Q8SAB7 (/IMP)
Regulation of cytoskeleton organization GO:0051493
Any process that modulates the frequency, rate or extent of the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures.
1 Q8SAB7 (/IMP)

There are 5 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.
1 Q8SAB7 (/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 Q8SAB7 (/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 Q8SAB7 (/IDA)
Extrinsic component of membrane GO:0019898
The component of a membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region.
1 Q8SAB7 (/IDA)
Endoplasmic reticulum exit site GO:0070971
An endoplasmic reticulum part at which COPII-coated vesicles are produced.
1 Q8SAB7 (/IDA)
