OverviewNCBI Gene

This gene is a member of the potassium-dependent sodium/calcium exchanger family and encodes an intracellular membrane protein with 2 large hydrophilic loops and 2 sets of multiple transmembrane-spanning segments. Sequence variation in this gene has been associated with differences in skin pigmentation. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SLC24A5 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 SLC24A5 as an antibody target. Whether an autoantibody or antibody against SLC24A5 could matter depends on whether native SLC24A5 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SLC24A5 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label SLC24A5 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
