Anti-ARGEF15 antibodies enable researchers to detect and measure the ARGEF15 antigen in biological samples. This target is a reported synonym of the ARHGEF15 gene, which encodes Rho guanine nucleotide exchange factor 15. This protein is known to function in GTPase activation and GPCR signaling pathways, among other biological roles. The human version of ARGEF15 has a canonical amino acid length of 841 residues and a protein mass of 91.9 kilodaltons. It is reported to be localized in the cell projections of cells. Other names for this target antigen include E5 and Ephexin5.
