hA was incubated with cells for 24 hours, cells fixed and its trafficking and association with cellular organelles, cytosolic and nuclear proteins was analyzed by indirect immunocytochemistry. Association of hA or lack of it with lysosomes (LAMP1), mitochondria (Mitotracker-MITO), Golgi (GM130), heat shock protein (HSP70) and ubiquitin (PD41) is shown. Representative cells in which hA accumulates in LAMP2 positive perinuclear compartments and interacts with ubiquitin in cytosol and nucleus are indicated by arrows.
