Senile plaques consisting of β-amyloid (Aβ) and neurofibrillary tangles composed of hyperphosphorylated tau are major pathological hallmarks of Alzheimer’s disease (AD). Elucidation of factors that modulate Aβ generation and tau hyperphosphorylation is crucial for AD intervention. Here we identify a novel mouse gene Fg01 that originated through retroposition of ribosomal protein S23. We demonstrate that FG01 protein reduces the levels of Aβ and tau phosphorylation by interacting with adenylate cyclases to activate cAMP/PKA and thus inhibit GSK-3 activity. The function of Fg01 is demonstrated in cells of various species including human, and in transgenic mice overexpressing FG01. Furthermore, the AD-like pathologies of triple transgenic AD mice were improved and levels of synaptic maker proteins increased after crossing them with Fg01 transgenic mice. Our studies reveal a new target/pathway for regulating AD pathologies and uncover a novel retrogene and its role in regulating protein kinase pathways.
