Description
Protein kinases are enzymes that transfer a phosphate group from a phosphate donor, generally the g phosphate of ATP, onto an acceptor amino acid in a substrate protein. By this basic mechanism, protein kinases mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. The tyrosine kinase (TK) group is mainly involved in the regulation of cell-cell interactions such as differentiation, adhesion, motility and death. There are currently about 90 TK genes sequenced, 58 are of receptor protein TK (e.g. EGFR, EPH, FGFR, PDGFR, TRK, and VEGFR families), and 32 of cytosolic TK (e.g. ABL, FAK, JAK, and SRC families).

Descripción
Muscle-associated receptor tyrosine kinase (MUSK) is a critical protein in the formation and maintenance of the neuromuscular junction (NMJ), the synapse between motor neurons and muscle fibers. MUSK is essential for the proper functioning of the NMJ, playing a pivotal role in the signaling pathways that govern the assembly and stability of this specialized synapse. The NMJ is crucial for muscle contraction and overall motor function, and disruptions in MUSK function can lead to severe neuromuscular diseases. MUSK is encoded by the MUSK gene, located on chromosome 9 in humans. The protein belongs to the receptor tyrosine kinase family and is highly conserved across species, reflecting its essential role in muscle biology. MUSK activation is tightly regulated and involves interactions with several other proteins, including agrin, low-density lipoprotein receptor-related protein 4 (LRP4), and downstream effectors such as rapsyn.

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).
