    ..These results suggest that liprin-alpha functions as a KIF1A receptor, linking KIF1A to various liprin-alpha-associated proteins for their transport in neurons. ..

    ..These data indicate a novel mechanism of synaptic plasticity in which activation of M1 receptors results in AMPAR endocytosis, via a mechanism involving interactions between GluA2, GRIP and liprin-alpha. ..
