There are a number of ELISA Kits available for the measurement of EFGM, another term for the human protein, G elongation factor mitochondrial 1. Other synonyms may include: elongation factor G mitochondrial, G translation elongation factor mitochondrial, mitochondrial elongation factor G, mitochondrial elongation factor G1, EFG, EFG1, and EFGM. It is encoded by the GFM1 gene to yield a protein 751 amino acids in length and 83.5 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the TRAFAC class translation factor GTPase superfamily, Classic translation factor GTPase family, EF-G/EF-2 subfamily. Versions of EFGM are present in other organisms, including: Mouse, Rat, Arabidopsis.
