KCNJ2
KCNJ2 (pronounced as K-C-N-J-Two) is a gene that provides instructions for making a protein that forms a channel across cell membranes. This channel, known as an inward rectifying potassium channel, allows potassium ions to flow into cells.
Etymology
The term "KCNJ2" is an abbreviation for Potassium Voltage-Gated Channel Subfamily J Member 2. The name is derived from its function and classification in the family of genes that encode potassium channels.
Function
The KCNJ2 gene provides instructions for making a protein that is critical for maintaining the normal function of cardiac muscle cells and muscle contractions. This protein forms a channel that controls the flow of potassium ions into cells, which is essential for maintaining the normal function of heart and muscle cells.
Related Terms
- Potassium Channel: A type of protein that allows potassium ions to pass through cell membranes.
- Ion Channel: A protein that allows ions to pass through cell membranes.
- Cardiac Muscle Cells: The type of cells that make up the heart muscle.
- Muscle Contraction: The process by which muscle cells generate force.
Associated Conditions
Mutations in the KCNJ2 gene can lead to conditions such as Andersen-Tawil Syndrome and Short QT Syndrome, both of which can cause heart rhythm disorders.
