Ras-Specific Guanine Nucleotide-Releasing Factor 1

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Ras-specific guanine nucleotide-releasing factor 1 (1273 aa, ~145 kDa) is encoded by the human RASGRF1 gene. This protein plays a role in guanine nucleotide exchange for Ras proteins.
