Abstract
GPNMB is a protein that is related to antiapoptotic mechanisms and recent studies suggest its neuroprotective role. GPNMB can be cleaved and its extracellular fragment interacts with a transmembrane protein called Na+/K+-ATPase (NKA). NKA is essential to electrolytic control of the cell and also has a signaling function that influences in inflammatory processes. Several studies suggest th…
