Name Ras-specific guanine nucleotide-releasing factor 2
Synonyms
  1. Ras guanine nucleotide exchange factor 2
  2. Ras-GRF2
Gene Name RASGRF2
Protein Type Unknown
Biological Properties
General Function Involved in Rho guanyl-nucleotide exchange factor activity
Specific Function 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
