Summaries for MUSK Gene

Entrez Gene Summary for MUSK Gene

  • 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]

GeneCards Summary for MUSK Gene

MUSK (Muscle, Skeletal, Receptor Tyrosine Kinase) is a Protein Coding gene. Diseases associated with MUSK include musk-related congenital myasthenic syndrome and progressive bulbar palsy. Among its related pathways are GPCR Pathway and Akt Signaling. GO annotations related to this gene include protein tyrosine kinase activity and transmembrane receptor protein tyrosine kinase activity. An important paralog of this gene is ALK.

UniProtKB/Swiss-Prot for MUSK Gene

  • 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 (PubMed:25537362). 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. May regulate AChR phosphorylation and clustering through activation of ABL1 and Src family kinases which in turn regulate MUSK. DVL1 and PAK1 that form a ternary complex with MUSK are also important for MUSK-dependent regulation of AChR clustering. May positively regulate Rho family GTPases through FNTA. Mediates the phosphorylation of FNTA which promotes prenylation, recruitment to membranes and activation of RAC1 a regulator of the actin cytoskeleton and of gene expression. Other effectors of the MUSK signaling include DNAJA3 which functions downstream of MUSK. May also play a role within the central nervous system by mediating cholinergic responses, synaptic plasticity and memory formation (By similarity).

    Molecular mass:

    Quaternary structure:
    • Monomer (By similarity). Homodimer (Probable). Interacts with LRP4; the heterodimer forms an AGRIN receptor complex that binds AGRIN resulting in activation of MUSK (By similarity). Forms a heterotetramer composed of 2 DOK7 and 2 MUSK molecules which facilitates MUSK trans-autophosphorylation on tyrosine residue and activation. Interacts (via cytoplasmic part) with DOK7 (via IRS-type PTB domain); requires MUSK phosphorylation. Interacts with DVL1 (via DEP domain); the interaction is direct and mediates the formation of a DVL1, MUSK and PAK1 ternary complex involved in AChR clustering (By similarity). Interacts with PDZRN3; this interaction is enhanced by agrin (By similarity). Interacts with FNTA; the interaction is direct and mediates AGRIN-induced phosphorylation and activation of FNTA (By similarity). Interacts with CSNK2B; mediates regulation by CK2 (By similarity). Interacts (via the cytoplasmic domain) with DNAJA3 (By similarity). Interacts with NSF; may regulate MUSK endocytosis and activity (By similarity). Interacts with CAV3; may regulate MUSK signaling (By similarity). Interacts with RNF31 (By similarity).

MUSK_HUMAN
  • Myasthenic syndrome, congenital, associated with acetylcholine receptor deficiency (CMS-ACHRD) [MIM:608931]: A post-synaptic congenital myasthenic syndrome. Congenital myasthenic syndromes (CMS) are inherited disorders of neuromuscular transmission that stem from mutations in presynaptic, synaptic, or postsynaptic proteins. {ECO:0000269 PubMed:15496425, ECO:0000269 PubMed:19949040, ECO:0000269 PubMed:20371544, ECO:0000269 PubMed:23326516, ECO:0000269 PubMed:24183479}. Note=The disease is caused by mutations affecting the gene represented in this entry. MUSK mutations lead to decreased agrin-dependent AChR aggregation, a critical step in the formation of the neuromuscular junction.
  • Fetal akinesia deformation sequence (FADS) [MIM:208150]: A clinically and genetically heterogeneous group of disorders with congenital malformations related to impaired fetal movement. Clinical features include fetal akinesia, intrauterine growth retardation, polyhydramnios, arthrogryposis, pulmonary hypoplasia, craniofacial abnormalities, and cryptorchidism. {ECO:0000269 PubMed:25537362, ECO:0000269 PubMed:25612909}.
