RASGRF2 (RAS Protein-Specific Guanine Nucleotide-Releasing Factor 2): RASGRF2 is a gene that encodes a protein acting as a guanine nucleotide exchange factor to activate RAS proteins, playing a key role in signal transduction. It is involved in synaptic plasticity and memory formation in the brain. Dysregulation of RASGRF2 may influence cognitive functions and contribute to the development of certain types of cancer.
