Neuronal-specific domain stabilization

Mechanistic description

Axon initial segment (AIS) infrastructure provides additional regulatory context that consolidates MAP-established domains; in fibroblasts, domains are less stable without this architectural support

Prediction: Transplanting AIS components into fibroblasts will produce more robust and long-lasting tau/MAP6 domain segregation

Evidence against (2)

Ankyrin-G and AIS organization depend on many binding partners, making ANK2-only domain stabilization an incomplete model of neuronal compartment maintenance.

PMID:40563541 2025 Biomolecules
AIS abnormalities are emphasized in neurodevelopmental disorders, so evidence for direct neurodegenerative therapeutic relevance is indirect.
