OverviewNCBI Gene
This gene encodes a member of the the SLC39A family of divalent metal transporters that mediates the cellular uptake of manganese, zinc, iron, and cadmium. The encoded protein contains eight transmembrane domains, a histidine-rich motif, and a metalloprotease motif, and is expressed on the plasma membrane and the endocytic vesicle membrane. It is an important transporter of nontransferrin-bound iron and a critical regulator of manganese homeostasis. Naturally occurring mutations in this gene are associated with neurodegeneration with brain iron accumulation and early-onset parkinsonism-dystonia with hypermanganesemia.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SLC39A14 as an antibody target. Whether an autoantibody or antibody against SLC39A14 could matter depends on whether native SLC39A14 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SLC39A14 is annotated at the cell surface, where native SLC39A14 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label SLC39A14 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
