OverviewNCBI Gene
Enables gamma-tubulin binding activity. Involved in cellular response to acidic pH; negative regulation of adiponectin secretion; and regulation of protein localization to cell surface. Located in several cellular components, including microtubule organizing center; mitochondrial outer membrane; and nuclear speck. [provided by Alliance of Genome Resources, Jul 2025]

Whether an antibody against RAB11FIP5 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 RAB11FIP5 as an antibody target. Whether an autoantibody or antibody against RAB11FIP5 could matter depends on whether native RAB11FIP5 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
RAB11FIP5 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 RAB11FIP5 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
