Introduction
KCNE1 (MinK) is a single transmembrane segment protein that assembles with KCNQ1 to form cardiac I(Ks) potassium channels. It modulates channel gating and is essential for normal cardiac repolarization. In the nervous system, KCNE1 and related KCNE subunits play important roles in neuronal excitability, synaptic function, and may contribute to neurodegenerative disease processes. This page covers the molecular biology, function, and therapeutic implications of KCNE1. [@roepke2019]
Gene Information
Protein Structure
KCNE1 is a small single-pass membrane protein:
Molecular Weight: 14.3 kDa
Transmembrane Domain: Single α-helix spanning the membrane
N-terminus: Extracellular, glycosylated
C-terminus: Intracellular, involved in channel modulation
Assembly: Forms complexes with KCNQ1 ( Kv7.1) alpha subunits
The protein acts as a regulatory subunit, altering the gating kinetics and pharmacological properties of the channel complex. Each KCNE1 subunit associates with four KCNQ1 subunits to form the I(Ks) channel.
Molecular Function
Ion Channel Modulation
KCNE1 modulates potassium channel function:
KCNQ1 Assembly: Co-assembles with KCNQ1 to form I(Ks) channels
