Alpha-ENaC is an alias for the gene, Sodium channel, non voltage gated 1 alpha subunit, in humans. Other names include: Amiloride-sensitive sodium channel subunit alpha; Epithelial Na(+) channel subunit alpha; Alpha-ENaC; ENaCA; Nonvoltage-gated sodium channel 1 subunit alpha; SCNEA; Alpha-NaCH; BESC2; ENaCalpha; SCNN1. The encoded protein has an amino acid length of 669 and a mass of 75.7 kDa. Other isoforms may exist. Alpha-ENaC is a member of the Amiloride-sensitive sodium channel (TC 1.A.6) family, SCNN1A subfamily. This gene shares homology with other species, including: Frog.
