LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LY6H 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 LY6H as an antibody target. Whether an autoantibody or antibody against LY6H could matter depends on whether native LY6H is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LY6H is annotated at the cell surface, where native LY6H is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.

Annotation status

The present source text does not explicitly label LY6H as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.

Seroatlas is the reference for exploring autoantibody and antibody serology at the human-protein level: the autoreactome and human serome, multiplex serology (HuProt, HuScan, VirScan, PhIP-Seq).
