Musk Gene Summary [Rat]
Enables protein kinase binding activity and protein tyrosine kinase activity. Involved in several processes, including positive regulation of synaptic assembly at neuromuscular junction; positive regulation of synaptic transmission; and regulation of macromolecule metabolic process. Located in cell projection; external side of plasma membrane; and neuromuscular junction. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 9 and fetal akinesia deformation sequence syndrome 1. Orthologous to human MUSK (muscle associated receptor tyrosine kinase). [provided by Alliance of Genome Resources, Jul 2025]
