Kcne1 Protein plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
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.

KCNE1 is a small single-pass membrane protein:
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.
KCNE1 modulates potassium channel function:
KCNE1 is expressed in:
In the brain, KCNE1 is expressed in:
| Condition | Relationship | Mechanism |
|---|---|---|
| Jervell and Lange-Nielsen Syndrome | Loss-of-function mutations | Cardiac arrhythmia, deafness |
| Long QT Syndrome | Gain-of-function mutations | Prolonged QT interval |
| Epilepsy | Risk variants | Altered neuronal excitability |
| Alzheimer's Disease | Altered expression | Network dysfunction |
