General description

The receptor-associated protein of the synapse (RAPSYN) is a peripheral membrane protein located in the skeletal muscles. It is co-localized along with nicotinic acetylcholine receptors (nAChRs) at the postsynaptic membrane due to the influence of neural agrin. Rapsyn consists of a myristoylated N-terminal, seven putative tetratricopeptide repeats, a coiled-coil domain, the RING-H2 domain, and the consensus sequence for phosphorylation.


whole purified rapsyn from Torpedo californica electric organ postsynaptic membrane.


Monoclonal Anti-Rapsyn antibody produced in mouse has been used in western blotting (0.5 μg/ml ) and immunocytochemistry (1:200).

Biochem/physiol Actions

The receptor-associated protein of the synapse (RAPSYN) participates in assembling the structure of the nicotinic postsynaptic membrane. It is required for the functioning of the neuromuscular junction. Mutations in the RAPSN gene are associated with endplate acetylcholine-receptor deficiency and Myasthenic syndrome.

Physical form

Solution in phosphate buffered saline containing 1.0 mg/mL BSA and 0.05% sodium azide.

Congenital myasthenic syndromes (CMSs) stem from genetic defects in endplate (EP)-specific presynaptic, synaptic, and postsynaptic proteins. The postsynaptic CMSs identified to date stem from a deficiency or kinetic abnormality of the acetylcholine receptor (AChR). All CMSs with a kinetic abnormality
