Gene Review

ATP13A2  -  ATPase type 13A2

Homo sapiens

Synonyms: CLN12, HSA9947, KRPPD, PARK9

Lysosomal protein mutated in a familial recessive form of parkinsonism with dementia (Kufor-Rakeb syndrome) [1], and certain forms of neuronal ceroid lipofuscinosis [2].


ATP13A2 knockdown models of recessive parkinsonism exhibit mitochondrial abnormalities [3] [4], due to suppression of autophagic quality control of mitochondria [3]. Increased sensitivity to cations such as manganese have also been reported [5] [6]
