OverviewNCBI Gene

The protein encoded by this gene functions as a transcription factor regulator in the transcriptional pathway for human cognition. It is a partner of the alpha subunit of the GA-binding protein transcription factor. Mutations in this gene cause mild autosomal recessive intellectual disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against METTL23 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 METTL23 as an antibody target. Whether an autoantibody or antibody against METTL23 could matter depends on whether native METTL23 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

METTL23 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 METTL23 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
