OverviewNCBI Gene

This gene encodes a cytoplasmic protein that acts as a tumor suppressor but also plays a key role in cell proliferation and the innate immune response to viral infection. The encoded protein contains an N-terminal sterile alpha motif domain. Naturally occurring mutations in this gene are associated with myeloid disorders such as juvenile myelomonocytic leukemia, acute myeloid leukemia, and myelodysplastic syndrome. Naturally occurring mutations are also associated with hepatitis-B related hepatocellular carcinoma, normophosphatemic familial tumoral calcinosis, and ataxia-pancytopenia syndrome.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SAMD9L 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 SAMD9L as an antibody target. Whether an autoantibody or antibody against SAMD9L could matter depends on whether native SAMD9L is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SAMD9L 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 SAMD9L as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
