RASGRF2 (RAS Protein-Specific Guanine Nucleotide-Releasing Factor 2): RASGRF2 is a guanine nucleotide exchange factor that activates RAS proteins, playing a crucial role in signal transduction. It is involved in synaptic plasticity and memory formation in the brain. Dysregulation of RASGRF2 has been associated with the development of certain types of cancer and cognitive functions.
