Activity-dependent MAP6 scaffolding at synapses

Mechanistic description

MAP6 may scaffold signaling complexes at synapses in an activity-dependent manner, linking NMDA receptor activation to cytoskeletal remodeling via its multiple functional domains

Prediction: MAP6 will physically associate with synaptic signaling proteins in a phosphorylation-dependent manner, and LTP-inducing stimulation will recruit MAP6 to dendritic spines
