Protein UniProt: O15146

Protein SigNET: O15146

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human MuSK sequence peptide Cat. No.: PE-04ABM80

Antibody Immunogen Sequence: SADY(pY)KAN(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues S752 to N759; In protein kinase catalytic domain activation T-loop between subdomains VII and VIII.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: 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. MuSK is necessary for neuromuscular junction formation. 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. Musk has been linked with the development of lung neuroendocrine carcinomas.
