OverviewNCBI Gene
This gene encodes a member of a subfamily of Ras-related GTPases. The encoded protein is involved in regulating p38 MAPK-dependent signaling cascades related to cellular stress. This protein also cooperates with nerve growth factor to promote neuronal development and regeneration. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2012]

Whether an antibody against RIT1 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 RIT1 as an antibody target. Whether an autoantibody or antibody against RIT1 could matter depends on whether native RIT1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
RIT1 is annotated at the cell surface, where native RIT1 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 RIT1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
