| abstractText | We purified and characterized a novel axonal growth-related molecule, neurin-1, which is anchored to the surface membrane via a phosphatidylinositol (PI) linkage. This molecule was detected by a combination of phosphatidylinositol-specific phospholipase C (PI-PLC) treatment from detergent-soluble mouse brain membranes and subsequent Western blot analysis with monoclonal antibody (MAb 2A). Neurin-1 is immunologically distinct from other known axonal growth associated surface glycoproteins. In immunoblots of embryonic mouse brain membrane, the MAb 2A recognized a single band at approximately 68 kDa, and showed that neurin-1 is mainly associated with fiber-containing regions of developing embryonic mouse brain. Expression is immunohistochemically similar to that of cell adhesion molecule L1, but in comparison, neurin-1 appears somewhat later. Late in embryonic development, neurin-1 appeared to be more stage- and region-specific. Its precise localization at the neural cell surface membranes was confirmed by immuno-electron microscopy using labeled and cultured live nerve cells. Neurin-1 was found only on the surface of the axon and growth cone. Neurin-1, otherwise termed PI anchor protein, corresponds closely in function to the other PI-anchored cell adhesion molecules. Anti-neurin-1 antibody (MAb 2A), however, perturbs the axonal growth and neural cell migration from the astrocyte feeder layer cultures. These results suggest that neurin-1 is one of the important cell surface molecules mediated in the neuron and glial cell interaction. |
