A/Prof Apaja is a principal investigator of Organelle Proteostasis Diseases laboratory at the Molecular and Biomedical Sciences and South Australian Health and Medical Research Institute.
Physiological conditions such as ageing, inflammation, stress insults as well as many brain diseases, cancers and numerous Mendelian diseases are directly driven or cause a short or long-term dysbalance in protein homeostasis.
Our research is focused on finding ways to reprogramme Protein Homeostasis (Proteostasis) Stress in human diseases, specifically through cellular disposal and surveillance systems to adapt to changing physiological conditions.
We are focusing on identifying key proteostasis networks, compounds and post-translational modifications in transport, recognition and disposal of membrane organelle/protein targets in neurodegenerative and -developmental diseases and cancers.
My laboratory combines screenings, omics and protein networks, testing of small molecule compounds, protein and membrane organelle microscopy with other biochemical and cell biological approaches in disease models.
