  • localized, at least in part, to lysosomes where it may participate in the ATP-dependent transport of cations across vesicular membranes
  • localized to a number of acidic vesicular compartments within cortical neurons, particularly lysosomes and endosomes
  • basic FUNCTION
  • having a ATPase activity, coupled to transmembrane movement of ions, phosphorylative mechanism
  • protein with similarity to P-type ATPases
  • regulates mitochondrial bioenergetics through macroautophagy
  • is predicted to mediate the transport of heavy metal cations, including cadmium, nickel, manganese and selenium
  • role for ATP13A2 in regulating intracellular cation transport
  • may play a role in regulating calcium homeostasis
  • implicated in vesicular trafficking
