Crystal structure of the MuSK tyrosine kinase: insights into receptor autoregulation.
J.H.Till, M.Becerra, A.Watty, Y.Lu, Y.Ma, T.A.Neubert, S.J.Burden, S.R.Hubbard.
Muscle-specific kinase (MuSK) is a receptor tyrosine kinase expressed selectively in skeletal muscle. During neuromuscular synapse formation, agrin released from motor neurons stimulates MuSK autophosphorylation in the kinase activation loop and in the juxtamembrane region, leading to clustering of acetylcholine receptors. We have determined the crystal structure of the cytoplasmic domain of unphosphorylated MuSK at 2.05 A resolution. The structure reveals an autoinhibited kinase domain in which the activation loop obstructs ATP and substrate binding. Steady-state kinetic analysis demonstrates that autophosphorylation results in a 200-fold increase in k(cat) and a 10-fold decrease in the K(m) for ATP. These studies provide a molecular basis for understanding the regulation of MuSK catalytic activity and suggest that an additional in vivo component may contribute to regulation via the juxtamembrane region.

Figure 1. Overall Structure of the MuSK Cytoplasmic Domain(A) A ribbon diagram of the MuSK crystal structure, with b strands (numbered) shown in cyan and a helices (lettered) shown in red. The juxtamembrane segment (N terminal) and the activation loop (containing aAL) are colored green. The activation loop tyrosines, Tyr-750/754/755, are shown in ball and stick representation (black).(B) A stereo view of a Ca trace of MuSK in the same orientation as the diagram in (A). Every 10th residue is marked with a closed circle, and every 20th residue is labeled with the residue number.
