Dynamic palmitoylation controls the microdomain localization of the DKK1 receptors CKAP4 and LRP6.

abstract：:In a mouse model of Parkinson's disease, new evidence shows that l-DOPA, which is used to treat the symptoms of the disease but also causes dyskinesia, results in a persistent activation of the protein kinase mTOR (mammalian target of rapamycin) in a subset of striatal medium spiny neurons. Moreover, blockade of a spe...
