Potassium voltage-gated channel subfamily E member 1 is a protein that in humans is encoded by the KCNE1 gene.^[3]^[4]

Voltage-gated potassium channels (Kv) represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Their diverse functions include regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume.^[5]

KCNE1 is one of five members of the KCNE family of Kv channel ancillary or β subunits. It is also known as minK (minimal potassium channel subunit).
