GAP43 phospho S41
Function
This protein is associated with nerve growth. It is a major component of the motile 'growth cones' that form the tips of elongating axons. Plays a role in axonal and dendritic filopodia induction.
Post-translational modifications
Phosphorylated (By similarity). Phosphorylation of this protein by a protein kinase C is specifically correlated with certain forms of synaptic plasticity (By similarity).
Palmitoylated by ZDHHC3 (By similarity). Palmitoylation is regulated by ARF6 and is essential for plasma membrane association and axonal and dendritic filopodia induction (PubMed:14978216). Deacylated by LYPLA2 (PubMed:21152083).
