Selection of synaptic partners may be dependent on detected synaptic activity in the vicinity of the filopodium.
2.
Examples of PAK4-regulated cellular processes include, dynamic reorganization of actin, filopodium formation, embryonic development, supports stem cell-like phenotypes, and gene expression.
3.
After contact between dendritic filopodium and a neighboring axon has been established, the filopodium retracts and the head begins to swell, taking on a more spine-like morphology.
