FunFam 43: Ras guanine nucleotide exchange factor H

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
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 Q8IS16 (/IMP)
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 Q8IS16 (/IPI)

There are 5 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
Aggregation involved in sorocarp development GO:0031152
The process whose specific outcome is the progression of the aggregate over time, from its formation to the point when a slug is formed. Aggregate development begins in response to starvation and continues by the chemoattractant-mediated movement of cells toward each other. The aggregate is a multicellular structure that gives rise to the slug.
1 Q8IS16 (/IMP)
Chemotaxis to cAMP GO:0043327
The directed movement of a motile cell or organism in response to the presence of 3',5'-cAMP.
1 Q8IS16 (/IMP)
Positive regulation of Ras protein signal transduction GO:0046579
Any process that activates or increases the frequency, rate or extent of Ras protein signal transduction.
1 Q8IS16 (/IMP)
Positive regulation of protein serine/threonine kinase activity GO:0071902
Any process that increases the rate, frequency, or extent of protein serine/threonine kinase activity.
1 Q8IS16 (/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 Q8IS16 (/IMP)

There are 1 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
Ras guanyl-nucleotide exchange factor complex GO:1905742
A protein complex which is capable of Ras guanyl-nucleotide exchange factor activity.
