These H-GRF55 ELISA kits are immunodetection tools for measuring the levels of H-GRF55 in biological samples. H-GRF55 is an alias of the human RASGRF1 gene, which encodes the protein, Ras protein specific guanine nucleotide releasing factor 1. Notably, H-GRF55 is known to play a role in GTPase activation and neuronal development, among other functions. The RASGRF1 protein is 1273 amino acid residues in length and 145.2 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. This protein is known to be ubiquitinated and phosphorylated. Other names for this target antigen include CDC25, CDC25L, and GNRP.
