Neuronal pathfinding is abnormal in mice lacking the neuronal growth cone protein GAP-43.
and CAP-23 together induce up to 60 times as much nerve regrowth as either engenders alone, says coauthor J.
Two such proteins, MARCKS (myristoylated alanine-rich C-kinase substrate) and GAP-43
(growth-associated protein-43), amass in the spaces, or synapses, between brain cells and apparently affect the maturation and shape of the synapses, Routtenberg says.
