Question

Quizplus · Accepted Answer

Rapsyn is a protein that physically holds acetylcholine receptors together in place at the neuromuscular junction. MuSK and LRP4 are necessary for the clustering of acetylcholine receptors, but they do not physically hold the receptors in place. Agrin stimulates the clustering of acetylcholine receptors, but it also does not physically hold the receptors in place.
