OverviewNCBI Gene

The Drosophila segment polarity gene lin encodes a protein, lines, which plays important roles in development of the epidermis and hindgut. This gene encodes a protein containing a lines-like domain. This gene is located on chromosome 15 and clustered with the gene encoding ankyrin repeat and SOCS box-containing protein 7. Alternative splicing results in multiple transcript variants.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LINS1 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Protein binding partners of LINS1 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads LINS1 as an antibody target. Whether an autoantibody or antibody against LINS1 could matter depends on whether native LINS1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LINS1 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 LINS1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
