The human KCNQ1 gene encodes the pore-forming subunit of a voltage-gated potassium channel. Co-expression with minK, an auxiliary subunit, recapitulates native function in heterologous expression (CHO cells). KvLQT1/minK channels expressed in the heart are safety targets in congenital and acquired long QT syndromes.
