Fyn is a member of the Src family of non-receptor tyrosine kinases. It has an N-terminal myristoylation site, SH3, SH2, and kinase domains. The protein is regulated by phosphorylation and intramolecular interactions.
Fyn is involved in signal transduction, synaptic plasticity, and myelination. It phosphorylates NMDA receptor subunits, tau, and signaling proteins. Fyn is important for learning and memory formation.
Fyn is implicated in AD pathogenesis. A-beta activates Fyn, leading to NMDA receptor phosphorylation, excitotoxicity, and tau pathology. Fyn is also involved in demyelination in MS and contributes to neurodegeneration in PD.
Src family kinase inhibitors (dasatinib, saracatinib) have been investigated for AD. Saracatinib (AZD0530) reached clinical trials for AD but showed limited efficacy. Challenges include achieving central activity and avoiding toxicity.
