Short name=Ras-GRF1
Alternative name(s):
Guanine nucleotide-releasing protein
Short name=GNRP
Ras-specific nucleotide exchange factor CDC25
Gene names
Name:RASGRF1
Synonyms:CDC25, GNRP, GRF1
OrganismHomo sapiens (Human) [Reference proteome]
Taxonomic identifier9606 [NCBI]
Taxonomic lineageEukaryotaMetazoaChordataCraniataVertebrataEuteleostomiMammaliaEutheriaEuarchontogliresPrimatesHaplorrhiniCatarrhiniHominidaeHomo

Protein attributes

Sequence length1275 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Promotes the exchange of Ras-bound GDP by GTP. Ref.5

Subunit structure

Homooligomer and heterooligomer with RASGRF2. Interacts with USP8, thereby regulating its stability By similarity. Ref.4

Domain

The DH (DBL-homology) domain mediates interaction with RASGRF2.

Post-translational modification

Phosphorylated by PLK2, leading to ubiquitination and degradation by the proteasome By similarity. Ref.5

Ubiquitinated and degraded following phosphorylation by PLK2 By similarity.

Phosphorylated by SRC and LCK. Phosphorylation by LCK increases its capacity to stimulate the GDP/GTP exchange on Ras, whereas its phosphorylation by SRC seems not to have an effect on stimulation activity. Ref.5

Sequence similarities

Contains 1 DH (DBL-homology) domain.

Contains 1 IQ domain.

Contains 1 N-terminal Ras-GEF domain.

Contains 2 PH domains.

Contains 1 Ras-GEF domain.
