Ready-to-use ELISA kits are available for the detection of h-DRK1, an alias of the protein, potassium voltage-gated channel subfamily B member 1. The official gene symbol is KCNB1. The protein, with a mass of 95.9 kDa and length of 858 residues, is reported to be membrane-associated. It is a member of the Potassium channel family, B (Shab) (TC 1.A.1.2) subfamily, Kv2.1/KCNB1 sub-subfamily and may be known by other names, including: DRK1, voltage-gated potassium channel subunit Kv2.1, potassium voltage-gated channel Shab-related subfamily member 1, and delayed rectifier potassium channel 1.
