Ready-to-use ELISA kits are available for the detection of K+ voltage-gated channel, subfamily S, 1, an alias of the protein, potassium voltage-gated channel modifier subfamily S member 1. The official gene symbol is KCNS1. The protein, with a mass of 58.4 kDa and length of 526 residues, is reported to be membrane-associated. It is a member of the Potassium channel family, S (TC 1.A.1.2) subfamily, Kv9.1/KCNS1 sub-subfamily and may be known by other names, including: voltage-gated potassium channel subunit Kv9.1, potassium voltage-gated channel delayed-rectifier subfamily S member 1, delayed-rectifier K(+) channel alpha subunit 1.
