FunFam 29: Ras guanine nucleotide exchange factor E

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
Ras guanyl-nucleotide exchange factor activity GO:0005088
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Ras superfamily. 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 Q86G47 (/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 Q86G47 (/IPI)
Myosin II binding GO:0045159
Interacting selectively and non-covalently with a class II myosin, any member of the class of 'conventional' double-headed myosins that includes muscle myosin.
1 Q86G47 (/IPI)
Actin filament binding GO:0051015
Interacting selectively and non-covalently with an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.

There are 9 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
Thermotaxis GO:0043052
The directed movement of a motile cell or organism in response to a temperature gradient. Movement may be towards either a higher or lower temperature.
2 B0M0P8 (/IMP) Q8IS18 (/IMP)
Positive phototaxis GO:0046956
The directed movement of a cell or organism towards a source of light.
2 B0M0P8 (/IMP) Q8IS18 (/IMP)
Ras protein signal transduction GO:0007265
A series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state.
1 Q86G47 (/IDA)
Sorocarp development GO:0030587
The process whose specific outcome is the progression of the sorocarp over time, from its formation to the mature structure. The process begins with the aggregation of individual cells and ends with the mature sorocarp. The sorocarp is a structure containing a spore-bearing sorus that sits on top of a stalk. An example of this process is found in Dictyostelium discoideum.
1 B0M0P8 (/HMP)
Sorocarp development GO:0030587
The process whose specific outcome is the progression of the sorocarp over time, from its formation to the mature structure. The process begins with the aggregation of individual cells and ends with the mature sorocarp. The sorocarp is a structure containing a spore-bearing sorus that sits on top of a stalk. An example of this process is found in Dictyostelium discoideum.
1 Q86G47 (/IMP)
Regulation of myosin II filament assembly GO:0043520
Any process that modulates the frequency, rate or extent of the formation of a bipolar filament composed of myosin II molecules.
1 Q86G47 (/IDA)
Positive regulation of GTPase activity GO:0043547
Any process that activates or increases the activity of a GTPase.
1 Q86G47 (/IMP)
Activation of GTPase activity GO:0090630
Any process that initiates the activity of an inactive GTPase through the replacement of GDP by GTP.
1 Q8IS18 (/IMP)
Response to differentiation-inducing factor 1 GO:1903013
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a 1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl)hexan-1-one stimulus.

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.
1 Q86G47 (/IDA)
Cell cortex GO:0005938
The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
