HUKII is an alias for the gene, Potassium channel, voltage gated shaker related subfamily A, member 4, in humans. Other names include: Potassium voltage-gated channel subfamily A member 4; HPCN2; Voltage-gated K(+) channel HuKII; Voltage-gated potassium channel HBK4; Voltage-gated potassium channel HK1; Voltage-gated potassium channel subunit Kv1.4; HBK4; KCNA4L; KV1.4; PCN2. The encoded protein has an amino acid length of 653 and a mass of 73.3 kDa. Other isoforms may exist. HUKII is a member of the Potassium channel family, A (Shaker) (TC 1.A.1.2) subfamily, Kv1.4/KCNA4 sub-subfamily. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
