| DAP 1 was found to associate with hDLG , PSD 95 , NMDA R and adenomatous polyposis coli protein ( APC ) . ^^^ Furthermore , we found that DAP 1 is specifically expressed in the brain and colocalizes with PSD 95 and APC in mouse cerebellum . ^^^ CONCLUSION : Our findings suggest that DAP 1 may play several roles in the molecular organization of synapses and neuronal cell signalling by interacting with hDLG and PSD 95 , which in turn are associated with receptors , ion channels and APC . . ^^^ |
