Nav1.5

Nav1.5 is a specialized protein found in the heart’s muscle cells, functioning as a sodium channel. It allows sodium ions to enter the cells rapidly, initiating electrical signals that trigger heartbeats. This process is essential for maintaining a regular heartbeat and proper heart function. Proper functioning of Nav1.5 is crucial; mutations or malfunctions can lead to irregular heart rhythms or arrhythmias, which can sometimes cause serious health issues. Overall, Nav1.5 is vital for the electrical activity that keeps the heart beating efficiently and steadily.
