These Rho guanine nucleotide exchange factor (GEF) 40 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Rho guanine nucleotide exchange factor (GEF) 40 is an alias of the human ARHGEF40 gene, which encodes the protein, Rho guanine nucleotide exchange factor 40. Notably, Rho guanine nucleotide exchange factor (GEF) 40 is known to play a role in axon guidance and GPCR signaling pathways, among other functions. The ARHGEF40 protein is 1519 amino acid residues in length and 164.7 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 noted to be expressed at higher level in the central nervous system and skeletal muscle and greater abundance in fetal than adult brain. Other names for this target antigen include Rho guanine nucleotide exchange factor (GEF) 40.
