The responses of rain-forest vegetation on Secretary Island (Fiordland National Park) which was subjected to low but sustained browsing by red deer, are compared with those of the full range of mountain vegetation in Mt Aspiring National Park where deer numbers had been reduced substantially from previously high numbers. On Secretary Island the most palatable species have continued to decline W...
A muscle-specific receptor tyrosine kinase, designated MuSK, mediates agrin-induced aggregation of acetylcholine receptors at the vertebrate neuromuscular junction. cDNAs encoding Xenopus MuSK were isolated from embryonic cDNA libraries. The full-length MuSK cDNA encodes for a polypeptide of 948 amino acids and possesses the features unique to mammalian MuSK, including four Ig-like domains, C6 ...
Muscle-specific kinase (MuSK) is essential for each step in neuromuscular synapse formation. Before innervation, MuSK initiates postsynaptic differentiation, priming the muscle for synapse formation. Approaching motor axons recognize the primed, or prepatterned, region of muscle, causing motor axons to stop growing and differentiate into specialized nerve terminals. MuSK controls presynaptic di...
We describe a severe congenital myasthenic syndrome (CMS) caused by two missense mutations in the gene encoding the muscle specific receptor tyrosine kinase (MUSK). The identified MUSK mutations M605I and A727V are both located in the kinase domain of MuSK. Intracellular microelectrode recordings and microscopy studies of the neuromuscular junction conducted in an anconeus muscle biopsy reveale...
Myasthenia gravis (MG) is a severely debilitating autoimmune disease that is due to a decrease in the efficiency of synaptic transmission at neuromuscular synapses. MG is caused by antibodies against postsynaptic proteins, including (i) acetylcholine receptors, the neurotransmitter receptor, (ii) muscle-specific kinase (MuSK), a receptor tyrosine kinase essential for the formation and maintenan...
Muscle-specific kinase (MuSK) is critical for the synaptic clustering of nicotinic acetylcholine receptors (AChRs) and plays multiple roles in the organization and maintenance of neuromuscular junctions (NMJs). MuSK is activated by agrin, which is released from motoneurons, and induces AChR clustering at the postsynaptic membrane. Although autoantibodies against the ectodomain of MuSK have been...
