Ready-to-use ELISA kits are available for the detection of Kv8.1, an alias of the protein, potassium voltage-gated channel modifier subfamily V member 1. The official gene symbol is KCNV1. The protein, with a mass of 56.3 kDa and length of 500 residues, is reported to be membrane-associated. It is a member of the Potassium channel family, V (TC 1.A.1.2) subfamily, Kv8.1/KCNV1 sub-subfamily and may be known by other names, including: HNKA, voltage-gated potassium channel subunit Kv8.1, potassium channel subfamily V member 1, potassium channel Kv8.1, neuronal potassium channel alpha subunit HNKA, and KV2.3.
