OverviewNCBI Gene

This gene encodes a serine-threonine protein kinase. Serine-threonine kinases transfer phosphate molecules to the oxygen atoms of serine and threonine. A genomic deletion affecting this gene has been associated with Ellis-van Creveld syndrome, an autosomal recessive skeletal dysplasia. Alternative splicing results in multiple transcript variants.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against STK32B 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 STK32B as an antibody target. Whether an autoantibody or antibody against STK32B could matter depends on whether native STK32B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

STK32B 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 STK32B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
