The Rap guanine nucleotide exchange factor (GEF) 1 ELISA kits listed below utilize specific antibodies for the plate-based assay of Rap guanine nucleotide exchange factor (GEF) 1 in various samples. Rap guanine nucleotide exchange factor (GEF) 1 is another term for the RAPGEF1 gene, which encodes the protein, Rap guanine nucleotide exchange factor 1 in humans. It has been reported that Rap guanine nucleotide exchange factor (GEF) 1 plays a role in neuronal development, among other functions. Structurally, the RAPGEF1 protein is 1077 amino acid residues in length and 120.5 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the endosome of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. This protein is known to be phosphorylated. Other names for this target antigen include C3G, C3G, and GRF2. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
