OverviewNCBI Gene

Rho GTPase activating protein 5 negatively regulates RHO GTPases, a family which may mediate cytoskeleton changes by stimulating the hydrolysis of bound GTP. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against ARHGAP5 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 ARHGAP5 as an antibody target. Whether an autoantibody or antibody against ARHGAP5 could matter depends on whether native ARHGAP5 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ARHGAP5 is annotated at the cell surface, where native ARHGAP5 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 ARHGAP5 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
