The DOK7 gene provides instructions for making a protein that helps form connections between nerve cells and muscle cells at the neuromuscular junction. The neuromuscular junction is the area between nerve cells and muscle cells where signals are passed on to trigger muscle movement.
Normal function
The DOK7 gene provides instructions for making a protein that helps form connections between nerve cells and muscle cells at the neuromuscular junction. The neuromuscular junction is the area between nerve cells and muscle cells where signals are passed on to trigger muscle movement.
The Dok-7 protein participates in turning on (activating) a protein called MuSK that helps organize the various proteins that are important for developing and maintaining the neuromuscular junction. In particular, MuSK is involved in gathering a protein called the acetylcholine receptor (AChR) on the surface of the muscle cells at the neuromuscular junction. The AChR protein is critical for signaling between nerve and muscle cells.
