Ras-specific guanine nucleotide-releasing factor 2

Gene

Rasgrf2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Functions as a calcium-regulated nucleotide exchange factor activating both Ras and RAC1 through the exchange of bound GDP for GTP. Preferentially activates HRAS in vivo compared to RRAS based on their different types of prenylation. Functions in synaptic plasticity by contributing to the induction of long term potentiation.8 Publications

Miscellaneous

Preferentially activates HRAS in vivo compared to R-RAS based on their different types of prenylation.

Domaini

The Ras-GEF domain and the N-terminal Ras-GEF domain form a Ras-binding site and mediate Ras activation.By similarity
The IQ domain mediates the calcium-dependent interaction with calmodulin but is dispensable for the Ras-GEF activity.
The DH (DBL-homology) domain mediates interaction with RASGRF1 and probably EPB49 and is required for RAC1 activation.
