The following errors occur in this paper.

All instances of “JIP” alone should read “JNK-interacting protein”, whereas “JIP1” refers specifically to the JIP family protein also known as MAPK8IP1.

The legend for Fig. 9 B should read as follows: “(B) Total neurite length refers to the combined length of processes from a given cell. Means ± SEM from 4–8 experimental sets are shown (*, P < 0.02; **, P < 0.001; determined by t test).”
