Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads CD300LD-AS1 as an antibody target. Whether an autoantibody or antibody against CD300LD-AS1 could matter depends on whether native CD300LD-AS1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CD300LD-AS1 is annotated as secreted, so native CD300LD-AS1 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.

Annotation status

The present source text does not explicitly label CD300LD-AS1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
