Erg2 is an alias for the gene, Potassium channel, voltage gated eag related subfamily H, member 6, in humans. Other names include: Potassium voltage-gated channel subfamily H member 6; Ether-a-go-go-related gene potassium channel 2; ERG-2; Eag-related protein 2; Ether-a-go-go-related protein 2; hERG-2; hERG2; Voltage-gated potassium channel subunit Kv11.2; ERG2; Kv11.2. The encoded protein has an amino acid length of 994 and a mass of 109.9 kDa. Erg2 is a member of the Potassium channel family, H (Eag) (TC 1.A.1.20) subfamily, Kv11.2/KCNH6 sub-subfamily. This gene shares homology with other species, including: Yeast, Rat.
