Abstract

The correct targeting of proteins to axons and dendrites of neurons is essential for the proper development of the nervous system. L1CAM is a cell-adhesion molecule responsible for multiple aspects of neuronal development; mutations are known to result in a developmental syndrome characterized by cognitive and motor disabilities. We expressed wild-type L1CAM and known L1CAM mutant proteins, P941L and D544N, in cultured embryonic chick forebrain neurons and compared their cellular distributions. Preliminary data suggests that both the wild-type L1CAM and the P941L L1CAM mutant are targeted to axons in a similar fashion. In contrast, the D544N L1CAM mutant does not appear to reach the cell surface of the neuron.
