Listed are ELISA Kits for the detection of Nsk2, an alias name of muscle associated receptor tyrosine kinase. The human protein, encoded by the gene MUSK, is 869 amino acid residues long and has a mass of 97,056 daltons. However, there are up to 3 reported isoforms. It is an enzyme of the receptor protein-tyrosine kinase class and is a member of the Protein kinase superfamily, Tyr protein kinase family. This protein is reported to have a membrane cellular localization, and is glycosylated. The gene is associated with Myasthenic syndrome, congenital, 9, associated with acetylcholine receptor deficiency. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, chicken, and primate. This target may also be known as: muscle skeletal receptor tyrosine-protein kinase, muscle skeletal receptor tyrosine kinase, muscle-specific kinase receptor, muscle-specific tyrosine-protein kinase receptor, and muscle skeletal receptor tyrosine kinase.
