ARHGEF5 (Rho guanine nucleotide exchange factor (GEF) 5)
Rho guanine nucleotide exchange factor 5 (Arhgef5) is crucial for podosome formation, which are membrane protrusions that play a crucial role in cell adhesion and migration and extracellular matrix remodeling. There are 2-6 more copies in the human genome of Arhgef5 than in any other primate. The significance of these copies in human is unknown.
