Ready-to-use ELISA kits are available for the detection of EGF1, an alias of the protein, G elongation factor mitochondrial 1. The official gene symbol is GFM1. The protein, with a mass of 83.5 kDa and length of 751 residues, is reported to be mitochondrial. It is a member of the TRAFAC class translation factor GTPase superfamily, Classic translation factor GTPase family, EF-G/EF-2 subfamily and may be known by other names, including: EFG1, EFG, mitochondrial elongation factor G1, mitochondrial elongation factor G, G translation elongation factor mitochondrial, and elongation factor G mitochondrial, and EGF1.
