LocalizationUniProt · AlphaFold · HPA

Whether an antibody against VSTM2L 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 VSTM2L as an antibody target. Whether an autoantibody or antibody against VSTM2L could matter depends on whether native VSTM2L is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

VSTM2L is annotated as secreted, so native VSTM2L 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 VSTM2L as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
