The Rap guanine nucleotide exchange factor (GEF) 3 ELISA kits listed below utilize specific antibodies for the plate-based assay of Rap guanine nucleotide exchange factor (GEF) 3 in various samples. Rap guanine nucleotide exchange factor (GEF) 3 is another term for the RAPGEF3 gene, which encodes the protein, Rap guanine nucleotide exchange factor 3 in humans. It has been reported that Rap guanine nucleotide exchange factor (GEF) 3 plays a role in adaptive immune responses and angiogenesis, among other functions. Structurally, the RAPGEF3 protein is 923 amino acid residues in length and 103.8 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the membrane of the cell. In terms of tissue specificity, it is reported to be widely expressed with highest levels in adult kidney, heart, thyroid and brain, and fetal kidney. Other names for this target antigen include CAMP-GEFI, CAMP-GEFI, and EPAC. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
