The Rho guanine nucleotide exchange factor (GEF) 1 ELISA kits listed below are analytical tools for measuring concentrations of Rho guanine nucleotide exchange factor (GEF) 1 in various samples. Rho guanine nucleotide exchange factor (GEF) 1 is an alternative name for the human ARHGEF1 gene, which encodes the protein, Rho guanine nucleotide exchange factor 1. It has been mentioned that Rho guanine nucleotide exchange factor (GEF) 1 plays a role in GPCR signaling pathways, among other functions. Structurally, the ARHGEF1 protein is 912 amino acid residues in length and 102.4 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the cytoplasm of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be phosphorylated. Other names for this target antigen include GEF1, IMD62, and LBCL2. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
