The E5 ELISA kits listed below are analytical tools for measuring concentrations of E5 in various samples. E5 is an alternative name for the human ARHGEF15 gene, which encodes the protein, Rho guanine nucleotide exchange factor 15. It has been mentioned that E5 plays a role in GTPase activation and GPCR signaling pathways, among other functions. Structurally, the ARHGEF15 protein is described to be 841 amino acid residues in length and 91.9 kilodaltons in mass. It is localized to the cell projections of the cell. In terms of tissue specificity, it is reported to be expressed in the vascular smooth muscle of coronary artery. This protein is known to be ubiquitinated and phosphorylated. Other names for this target antigen include ARGEF15 and Ephexin5. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
