OverviewNCBI Gene

Netrin is included in a family of laminin-related secreted proteins. The function of this gene has not yet been defined; however, netrin is thought to be involved in axon guidance and cell migration during development. Mutations and loss of expression of netrin suggest that variation in netrin may be involved in cancer development. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against NTN1 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads NTN1 as an antibody target. Whether an autoantibody or antibody against NTN1 could matter depends on whether native NTN1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

NTN1 is annotated as secreted, so native NTN1 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 NTN1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
