OverviewNCBI Gene
This gene is a member of the RAB gene family which belongs to the RAS GTPase superfamily. The proteins in the family of RAS-related signaling molecules are small GTP-binding proteins that play important roles in the regulation of exocytotic and endocytotic pathways. This gene maps to the site of an ancestral telomere fusion event and may be a subtelomeric gene. Alternative splicing results in multiple transcript variants encoding different isoforms.

Whether an antibody against RABL2B 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 RABL2B as an antibody target. Whether an autoantibody or antibody against RABL2B could matter depends on whether native RABL2B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
RABL2B 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 RABL2B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
