Scientific Background: Human Musk is a protein-tyrosine kinase of the TK group of protein kinases in the Musk family. This kinase is moderate to highly expressed in most tested human tissues except in the bladder, brain, pericardium, pituitary, spinal cord, trachea and vagina where it is notably low. Orthologues of Musk are highly conserved in vertebrates and insects. MUSK is necessary for neuromuscular junction formation (1). Musk gene expression is highly regulated during neuromuscular junction and it is involved in intercellular communication present on the surface of cells that are activated by specific protein ligands. Musk members play a key role in growth and differentiation of those cell types. Agrin signals through Musk to cluster acetylcholine receptors on the postsynaptic membrane of the neuromuscular junction. Musk interacts with Dok7, which may regulates its phosphotransferase activity. Dok7 is essential for MUSK activation in cultured myotubes. Musk also plays a critical role in the development of normal blood vessels (2). Musk has been linked with the development of lung neuroendocrine carcinomas.
