PTEN has an N-terminal phosphatase domain, a C2 domain that mediates membrane association, and C-terminal regulatory regions. The protein is a tumor suppressor with both lipid and protein phosphatase activity.
PTEN is a major negative regulator of the PI3K/Akt signaling pathway. It dephosphorylates PIP3 to PIP2, inhibiting Akt activation and downstream signaling. PTEN regulates cell growth, survival, and metabolism. In neurons, PTEN modulates synaptic plasticity and axon guidance.
PTEN is implicated in neurodegenerative diseases through its regulation of cell survival pathways. In AD, PTEN activation may contribute to synaptic dysfunction. In PD, PTEN regulates dopaminergic neuron survival. PTEN deletion is neuroprotective in some models.
PTEN inhibitors are being developed for cancer, but could have applications in neuroprotection. However, PTEN's tumor suppressor function raises safety concerns. Novel approaches targeting PTEN signaling specifically in neurons are needed.
