OverviewNCBI Gene

Organic ion transporters, such as SLC22A15, transport various medically and physiologically important compounds, including pharmaceuticals, toxins, hormones, neurotransmitters, and cellular metabolites. These transporters are also referred to as amphiphilic solute facilitators (ASFs).[supplied by OMIM, Apr 2004]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SLC22A15 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads SLC22A15 as an antibody target. Whether an autoantibody or antibody against SLC22A15 could matter depends on whether native SLC22A15 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SLC22A15 is annotated at the cell surface, where native SLC22A15 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 SLC22A15 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
