Mutations in the human L1CAM gene cause X-linked Hydrocephalus and MASA syndrome. In vitro studies have shown the L1 cytoplasmic domain (L1CD) is involved in L1 trafficking, neurite branching, signaling, and interactions with the cytoskeleton. L1cam knock-out (L1KO) mice have hydrocephalus, a small cerebellum, hyperfasciculation of corticothalamic tracts and abnormal peripheral nerves. To explore the function of the L1CD, we made three new mice lines in which different parts of the L1CD have been altered. In all mutant lines L1 protein is expressed and transported into the axon. Interestingly, these new L1CD mutant lines display normal brain morphology. However, the expression of L1 protein in the adult is dramatically reduced in the two L1CD mutant lines that lack the ankyrin-binding region and they show defects in motor function. Therefore, the L1CD is not responsible for the major defects observed in L1KO mice, yet it is required for continued L1 protein expression and motor function in the adult.
