Related Product Information for anti-MuSK antibody

Receptor tyrosine kinase which plays a central role in the formation and the maintenance of the neuromuscular junction (NMJ), the synapse between the motor neuron and the skeletal muscle. Recruitment of AGRIN by LRP4 to the MUSK signaling complex induces phosphorylation and activation of MUSK, the kinase of the complex. The activation of MUSK in myotubes regulates the formation of NMJs through the regulation of different processes including the specific expression of genes in subsynaptic nuclei, the reorganization of the actin cytoskeleton and the clustering of the acetylcholine receptors (AChR) in the postsynaptic membrane.

NCBI Description

This gene encodes a muscle-specific tyrosine kinase receptor. The encoded protein may play a role in clustering of the acetylcholine receptor in the postsynaptic neuromuscular junction. Mutations in this gene have been associated with congenital myasthenic syndrome. Alternatively spliced transcript variants have been described.[provided by RefSeq, Oct 2009]

Uniprot Description

MUSK: a receptor tyrosine kinase that is essential for the establishment and maintenance of the neuromuscular junction (NMJ). Its activation by agrin, a neuronally derived heparan-sulfate proteoglycan, and the agrin receptor (LRP4), leads to clustering of acetylcholine receptors on the postsynaptic side of the NMJ. Its activation by agrin requires Dok7, which interacts with the cytoplasmic portion of MuSK and activates its tyrosine kinase activity.
