OverviewNCBI Gene
Radixin is a cytoskeletal protein that may be important in linking actin to the plasma membrane. It is highly similar in sequence to both ezrin and moesin. The radixin gene has been localized by fluorescence in situ hybridization to 11q23. A truncated version representing a pseudogene (RDXP2) was assigned to Xp21.3. Another pseudogene that seemed to lack introns (RDXP1) was mapped to 11p by Southern and PCR analyses. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

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

Protein binding partners of RDX in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads RDX as an antibody target. Whether an autoantibody or antibody against RDX could matter depends on whether native RDX is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
RDX is annotated at the cell surface, where native RDX 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 RDX as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
