ATP13A3 (ATPase Cation Transporting 13A3) is a gene encoding a type V P-type ATPase that functions as a cation transporter with specificity for calcium and other divalent cations[1]. Located on chromosome 3q29, this protein is closely related to ATP13A2 (PARK9), which is linked to Kufor-Rakeb syndrome and early-onset Parkinson's disease[2]. ATP13A3 plays critical roles in cellular calcium homeostasis, lysosomal function, and autophagy regulation, all of which are pathways central to neurodegenerative disease pathogenesis.
The protein localizes to the endoplasmic reticulum and lysosomes, where it contributes to maintaining intracellular cation balance. Dysfunction of ATP13A3 has been associated with impaired lysosomal function and reduced clearance of alpha-synuclein, the hallmark protein of Parkinson's disease[3]. Additionally, ATP13A3 variants have been implicated in pulmonary hypertension, indicating its importance in vascular biology as well.
ATP13A3 encodes a member of the P-type ATPase cation transport family, specifically a type V P-type ATPase that localizes to the endoplasmic reticulum and lysosomes. This protein functions as a cation transporter with specificity for calcium and other divalent cations. ATP13A3 is closely related to ATP13A2 (PARK9), which is linked to Kufor-Rakeb syndrome and early-onset PD. The protein plays important roles in cellular calcium homeostasis, lysosomal function, and autophagy regulation.
Wide expression in brain, particularly in substantia nigra, hippocampus, and cortex. Also expressed in lung and cardiovascular tissues.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Parkinson's Disease | R474Q, A889T | Risk factor | Impaired lysosomal function, alpha-synuclein clearance |
| Pulmonary Hypertension | Dominant mutations | Autosomal dominant | Vascular smooth muscle proliferation |
