OverviewNCBI Gene

The GT6 glycosyltransferases gene family, which includes the ABO blood group (ABO; MIM 110300) and GLT6D1, shows a complex evolution pattern, with multiple events of gain and loss in different mammal species. In humans, the ABO gene is considered the sole functional member, although the O allele is null and is fixed in certain populations (summary by Casals et al. (2009) [PubMed 19218399]).[supplied by OMIM, Jan 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against GLT6D1 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 GLT6D1 as an antibody target. Whether an autoantibody or antibody against GLT6D1 could matter depends on whether native GLT6D1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

GLT6D1 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 GLT6D1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
