PTEN globally suppresses growth in multiple cell types and inhibits neuronal axon growth and branching. Brosig et al. describe a mechanism for developing neurons to inhibit PTEN function by upregulating PRG2 in the axon. Although the overall growth capacity of neurons remains constant, PRG2 redirects growth to axon branches.
