The ELISA kits listed below target MuSK, the symbol for the human gene, muscle associated receptor tyrosine kinase, and a member of the Protein kinase superfamily, Tyr protein kinase family. The protein has an enzyme classification of receptor protein-tyrosine kinase. The protein encoded by MUSK has a predicted amino acid length of 869, a mass of 97.1 kDa, and a membrane subcellular localization. There are currently 3 reported isoforms, as well as sites of glycosylation. Pathologic involvement is reported in Myasthenic syndrome, congenital, 9, associated with acetylcholine receptor deficiency. MUSK may also be known by the following names: FADS, muscle-specific tyrosine-protein kinase receptor, muscle-specific kinase receptor, muscle skeletal receptor tyrosine kinase, and muscle skeletal receptor tyrosine-protein kinase. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, plant, and other mammalian are available targets of several ELISA kits.
