Provided below are ELISA kits targeting receptor associated protein of the synapse, a human protein encoded by RAPSN. This protein is 412 amino acids long, with a mass of 46.3 kDa, and is a member of the RAPsyn family. 2 isoforms have been identified. This is reported to be a cytoplasmic and membrane protein. There is a noted implication in Myasthenic syndrome, congenital, 11, associated with acetylcholine receptor deficiency. Other alias names for this protein include: 43 kDa receptor-associated protein of the synapse, 43 kda postsynaptic protein, RING finger protein 205, acetylcholine receptor-associated 43 kda protein, CMS4C, RAPSYN, and RNF205.
