Probable cation-transporting ATPase 13A2 is an enzyme that in humans is encoded by the ATP13A2gene that is involved in the transport of divalent transition metal cations.[5][6][7] It appears to protect cells from manganese[8] and zinc toxicity,[9] possibly by causing cellular efflux and/or lysosomal sequestration; and from iron toxicity, possibly by preserving lysosome integrity against iron-induced lipid peroxidation.[10] However, it potentiates the toxic effects of cadmium and nickel on developing neurites,[11] and of the widely used herbicide paraquat[12] possibly by increasing polyamine uptake.[13]
Deficiency is associated with spastic paraplegia and Kufor-Rakeb syndrome, in which there is progressive parkinsonism with dementia.[14]
