Ready-to-use ELISA kits are available for the detection of RhoDGI, an alias of the protein, Rho GDP dissociation inhibitor alpha. The official gene symbol is ARHGDIA. The protein, with a mass of 23.2 kDa and length of 204 residues, is reported to be cytoplasmic. It is a member of the Rho GDI family and may be known by other names, including: NPHS8, HEL-S-47e, epididymis secretory sperm binding protein Li 47e, Rho GDP dissociation inhibitor (GDI) alpha, GDP-dissociation inhibitor aplysia RAS-related 1, and rho GDP-dissociation inhibitor 1, and RHOGDI-1.
