Erratum: We regret that, due to an administrative error, the cover photo that appears on the November 15, 1997 issue does not correspond to any articles in the issue. It is incorrectly credited to an article by Comu et al., “The Murine P84 Neural Adhesion Molecule Is SHPS-1, a Member of the Phosphatase-Binding Protein Family.” The authors of the cover photo are Karschin and Karschin. The corresponding paper will appear in Molecular and Cellular Neuroscience, Volume 10, Number 3/4, p 31. We apologize for this error and any inconvenience it may have caused our readers.
