FunFam 25: C3G guanyl-nucleotide exchange factor, isoform L

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 O77086 (/IMP)
Rap guanyl-nucleotide exchange factor activity GO:0017034
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rap 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 O77086 (/IDA)

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
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 O77086 (/IMP)
Somatic muscle development GO:0007525
The process whose specific outcome is the progression of the somatic muscle over time, from its formation to the mature structure. Somatic muscles are striated muscle structures that connect to the exoskeleton or cuticle.
1 O77086 (/IMP)
Muscle attachment GO:0016203
The developmental process in which a skeletal muscle attaches to its target (such as bone or body wall).
1 O77086 (/IMP)
Regulation of GTPase activity GO:0043087
Any process that modulates the rate of GTP hydrolysis by a GTPase.
1 O77086 (/IDA)
Positive regulation of GTPase activity GO:0043547
Any process that activates or increases the activity of a GTPase.
1 O77086 (/IDA)
Sarcomere organization GO:0045214
The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.
1 O77086 (/IMP)
