It may link the receptor to the underlying postsynaptic cytoskeleton, possibly by direct association with actin or spectrin (By similarity).Cell membranePeripheral membrane proteinCytoplasmic sidePostsynaptic cell membranePeripheral membrane proteinCytoplasmic sideCytoplasmCytoskeletonCytoplasmic surface of postsynaptic membranes.Expressed in muscle fibers and in neurons.A cysteine-rich region homologous to part of the regulatory domain of protein kinase C may be important in interactions of this protein with the lipid bilayer.Belongs to the RAPsyn family.Cell membraneCytoplasmCytoskeletonLipoproteinMembraneMetal-bindingMyristatePhosphoproteinPostsynaptic cell membraneReference proteomeRepeatSynapseTPR repeatZincZinc-fingerMGQDQTKQQIEKGLHLYQSNQTEKALQVWMRVLEKSADPAGRFRVLGCLITAHAEMGRYKDMLKFAVVQIDTARELEDPNYLTEGYLNLARSNEKLCEFQKTISYCKTCLNMQGTTVSLQLNGQVSLSMGNAFLGLSIFQKALECFEKALRYAHNNDDKMLECRVCCSLGNFYAQIKDYEKALFFPCKAAELVNDYGAGWSLKYRAMSQYHMAVAYRKLGRLADAMDCCEESMKIALQHGDRPLQALCLLCFADIHLSRRDVQTAFPRYDSAMSIMTEIGNRLGQIQVLLGVAKCWMIQKELDKALESIEKAQELAEGLGNKLGLLKLHCLCERIYRTKGLQQELRDHVVKFHECVEEMELYCGMCGESIGEKNNQLQALPCSHFFHLKCLQTNGTRGCPNCRRLSVKPGYV
