OverviewNCBI Gene

This gene encodes a loosely associated peripheral membrane protein related to the LanC family of bacterial membrane-associated proteins involved in the biosynthesis of antimicrobial peptides. This protein may play a role as a peptide-modifying enzyme component in eukaryotic cells. Previously considered a member of the G-protein-coupled receptor superfamily, this protein is now in the LanC family. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Nov 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LANCL1 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 LANCL1 as an antibody target. Whether an autoantibody or antibody against LANCL1 could matter depends on whether native LANCL1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LANCL1 is annotated at the cell surface, where native LANCL1 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 LANCL1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
