ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells
FEBS Open Bio, EarlyView.Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.
