We study the regulation of mRNA translation in brain function and disease. Of particular interest is alternative translation, where ribosomes use noncanonical start and stop codons and generate N- and C-terminal protein variants. Two key questions guide us: i) What roles do atypical protein variants play in the central nervous system?, and ii) How is translation impacted in neurological diseases? We have found that a C-terminally elongated variant of the water channel protein AQP4 is involved in the clearance of amyloid-beta from the brain. Current research focuses on AQP4 as well as additional protein variants and utilizes molecular biology, transcriptomics, translatomics, mouse genetics, stereotaxic surgeries, pharmacology, MRI, and behavioral assays. By studying previously uncharacterized protein variants, we aim to illuminate brain health and neurological disease from a new molecular perspective.
