LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SRMS can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

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

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